Another Goodfellas one:

Tommy's mom is played by Martin Scorsese's mom. And in her scene, the painting with the two dogs in the rowboat ("One dog goes one way, the other dog goes the other way, and this guy's sayin', 'Whadda ya want from me?'") was painted by the mother of Nicholas Pileggi, who wrote the book the movie was based on.
