It's Not Just You, Murray! (1964)

Now middle-aged, mobster Murray looks back at his humble beginnings as a bootlegger, and his rise to becoming wealthy and highly influential. Through it all, he talks about how much of his success and happiness is due to the support of his "friend" Joe.

Unfortunately, the only one who blindly believes that Joe is anything close to a friend is Murray himself, because it's obvious to everyone else that Joe not only back-stabs him at every chance, but is also sleeping with his wife.
