Im going to go ahead and attempt to make a list of all the Godfather or Goodfella references....
godfather\good fellas references
-When confronted over his attempted purchase of a gun and told that he cannot get to his Uncle Junior anyway because he is in police custody, AJ says it's "difficult, not impossible" - these same words are spoken by Rocco Lampone in The Godfather Part II in reference to assassinating Hyman Roth.
-When pitching Cleaver, Silvio, Christopher, and J.T. Dolan compare and contrast the film to The Ring, the Friday the 13th franchise, and Freddy Kruger movies, and Halloween as well as to The Godfather II, Saw and Ghostbusters franchises.
-In a rare session with Dr. Melfi, Carmela recalls her second date with Tony, in which he brought her father a $200 power drill as a gift. She says she knew there was "probably some guy with a broken arm" behind it and reflects on whether this made her like Tony less, or more. This mimics Bracco's own character's reaction in Goodfellas when she realized what Henry Hill really was early in their relationship.
-When Janice tells Tony he has changed and is "different" since the shooting, Tony responds: "Different how? How am I different?", which could be a throwback to Joe Pesci's character Tommy DeVito in the famous Goodfellas scene: "Funny how? How am I Funny?"
-The brief sound of a train moving in a subway during the scene where Gerry is murdered could be a nod to The Godfather.
-The closing scene of Remember When which depicts Uncle Junior sitting on an outdoor chair, lost in thought, as the screen slowly fades to black, is possibly a nod to the closing scene of The Godfather Part II, which shows Al Pacino as Michael Corleone in a similar pose. Michael Corleone's father Vito Corleone was memorably depicted stroking a cat in The Godfather.
-In addition, Tony's tomato plants in his yard are highly reminiscent of the ones Vito Corleone used to have in his gard
-Tony picks up A.J. at the police station and violently confronts him. In tears, A.J. calls his father a hypocrite because Tony admires Michael Corleone for avenging the attempted murder of his father in The Godfather. Tony, although touched by his son's intentions, tells him that he needs to grow up and that The Godfather is only a movie.
-When disposing of Emil Kolar's body, Christopher says to "Big Pussy," "Louis Brasi sleeps with the fishes." Pussy corrects him, "Luca Brasi." The character Brasi, as well as the famous phrase describing his death as "sleeps with the fishes," are from The Godfather.
-When Tony grabs Christopher after he was considering selling his life story into a biopic, he mentions mobster Henry Hill whose life story was documented in the true crime book Wiseguy: Life in a Mafia Family and subsequently adapted into Goodfellas.
-Richard Romanus plays Dr. Melfi's ex-husband, Richard LaPenna, and he talks to Dr. Melfi (played by Lorraine Bracco) that the American culture is giving Italian-Americans a bad name, and mentions Goodfellas to Melfi. Both Richard Romanus and Lorraine Bracco co-starred in a Martin Scorsese film, Romanus co-starred in Mean Streets and Bracco co-starred in Goodfellas.
-Christopher's shooting the bakery employee in the foot mirrors an "innocent" Spider's getting shot in the foot in Goodfellas. Michael Imperioliplays both Spider and Christopher.
-As revenge for embarrassing him, Tony, in reference to the scene in The Godfather Part II when a young Vito Corleoneholds a bag of guns for a young Peter Clemenza, fills a parcel with sand and asks Dr. Cusamano to hold on to it, in an attempt to worry Cusamano and his wife. The box is a source of concern to the Cusamanos, who think it may contain drugs or a weapon.
-The next day, Unidentified Black Males Rasheen Ray and Petite Clayborn again wait for Tony to appear at the newsstand. Tony stops to buy a newspaper and orange juice, echoing a scene in The Godfather wherein Vito Corleone buys oranges before an unsuccessful attempt on his life.
-Phillip Parisi's death is a reference to The Godfather (1972), when Paulie Gatto is shot and killed in the driver's seat of a car because of his role in the attempted murder of Vito Corleone. Also, as Philly gets in his car to leave home, his wife tells him, "Don't forget the pastries", a reference to the scene where Peter Clemenza's also wife tells him, "Don't forget the cannoli", before he drives off to see that Paulie is killed.
-While attempting to watch a bootleg version of The Godfather, Part II, Tony Soprano announces to his crew that he will be traveling to Naples
-Just as in the season opener, "Guy Walks Into a Psychiatrist's Office...", Silvio does his The Godfather Part III Michael Corleone impersonation in the dream, only in the dream he is referring to Pussy: "Our true enemy has yet to reveal himself".
-In his dream, Tony sees Pussy as a fish who notes that two other fish on either side of him are sleeping. The reference is to death, as in "sleeps with the fishes" from The Godfather, and it foreshadows Pussy's ultimate resting place, the ocean.
-The undertaker promises Tony that he will "use all [his] power, and all [his] skills" on Livia's behalf (presumably via cosmetics and embalming), Tony then tells him not to go overboard. This is a direct reference to The Godfather, wherein Don Vito Corleone commands the undertaker Amerigo Bonasera to "use all of your power and all of your skills" to beautify his eldest son Sonny Corleone's bullet-riddled corpse. The descending elevator camera angle used to introduce the undertaker is also taken directly from The Godfather.
-When Adriana learns that Christopher is about to be made, she becomes worried that it might be a pretext for a hit, but Christopher chides her for "watching too many movies." Soon after, after arriving at the basement location of the ceremony, Silvio tells Tony that Chris was nervous during the entire ride over, and this time, Tony kids Chris as the one who's "watching too many movies". This alludes to Goodfellas (in which Michael Imperioli appeared, as well as several other cast members of The Sopranos), where Tommy DeVito is lured to his death under the pretext of being made. A similar situation takes place in the movie Donnie Brasco, where Lefty (Al Pacino) fears he'll be the victim of a hit, but instead, his boss gives him a very unusual gift: a lion.
-Lorraine Bracco's character is raped by Jesus Rossi, or J. Rossi. In the film Goodfellas, Lorraine Bracco's character also has a nemesis named J. Rossi (Janice Rossi), whom her husband is sleeping with.
-The voiceover on the Mercedes TV commercial, which Tony watches before going to bed with Carmela and which makes him think of Gloria (who works as a saleswoman for a company that sells the cars), is voiced by Joe Mantegna, who also voices mob boss Fat Tony on The Simpsons, as well as played Joey Zaza in The Godfather Part III.
-When Jackie Aprile hears the petition of Carlo and Matush, he strikes a pose apparently modeled on that of Marlon Brando in the opening scene of The Godfather.
-One of the elderly hit men that Silvio and Christopher meet is Frank Crisci. Crisci is played by Richard Bright who also played Al Neri, a Corleone family member and assassin, in all three Godfather movies. In the episode, the character talks about killing a "Tommy Neri," who was Al Neri's nephew in The Godfather.
-When Tony comes to visit Ralphie, he is offered a bag of Florida oranges ("Florida's finest"). In The Godfather, oranges are present whenever characters are murdered, or die. Part of the episode revolves around an attempted hit on Ralphie in Florida.
-In his meeting with Dr. Melfi, Tony talks of how in the olden days mafia men would take their mistresses out on Fridays and their wives on Saturdays. This could be a reference to Goodfellas, in which Lorraine Bracco (Melfi) plays gangster Henry Hill's wife. Tony also almost matches Ray Liotta's dialogue from the film when, as Henry, he is explaining the same custom: ('Friday nights were for the wives, but Saturday was always for the girlfriends').
-The opening sequence of Season 5 of various shots of the Soprano home with autumn leaves blowing in the wind is an homage to the opening shots of The Godfather Part III, which portrayed the rundown Corleone compound in Lake Tahoe
At Carmela's house, due to Tonys removing the media system, the women enjoy snacks and wine instead of watching Casablanca. The next movie on their list is The Godfather.
-A.J.'s teacher calls A.J. "Fredo Corleone" in a conversation with Wegler, referring to Michael Corleone's less gifted older brother in The Godfather novels and films.
-The Test Dream episode makes multiple references to the film The Godfather. Annette Bening speaks the line, "I don't want my husband coming out of there with just his cock in his hand", referring to an almost-identical line spoken by Sonny Corleone. Afterwards, Tony's reaching behind the toilet tank for the non-existent gun is a reference to a similar scene with Michael Corleone. When Tony Blundetto shoots Phil Leotardo in Tony Soprano's dream, he exits the same make and brand car (Lincoln Continental) in a similar fashion to Sonny Corleone, during the famous toll-booth shooting scene.
-The scene with Christopher and Adriana where both of them are crying over the consequences of Adriana being an informant, including Chris' strangled wail of "Oh, God, what are we gonna do?!' mirror a very similar scene in the 1990 film Goodfellas where Henry and Karen Hill are falling apart at the realization they are in mortal danger from Paulie Cicero and his crew after Henry's narcotics bust.
-The scene with Tony Soprano sitting alone in his backyard reminiscing about his cousin closely resembles the ending scene of The Godfather Part II, in which Michael Corleone sits alone at his Lake Tahoe compound remembering a moment shared with his family.
-When Tony enters the bathroom stall, he reaches behind the vintage style toilet tank looking for a gun which is not there, an allusion to the The Godfather.
Both Tommy DeVito (Joe Pesci) in Goodfellas and Ralph Cifaretto (Joe Pantoliano) in The Sopranos unrepentantly cause horseplay injury to another person. Ralph hits Georgie in the eye with a chain and Tommy shoots Spider (Michael Imperioli) in the foot.
