Joe Pesci plays an old man who seems to be at a line read for a movie. Al Pacino plays Jimmy Hoffa and shouts a lot like those guys Al Pacino plays in films with Al Pacino in them, and Robert de Niro plays the guy that Robert de Niro plays in films with Robert de Niro in them.

They meet from time to time in booths at badly lit restaurants and talk to each other, and to Harvey Keitel who reprises the role of Harvey Keitel from other films with Harvey Keitel in them.

There are some familiar faces in the smaller parts. Jesse Plemons plays a young guy who can't believe he's in a scene with Al Pacino, and Anna Paquin plays the woman in the film.

You'll enjoy watching Robert de Niro play a 40 yr old with the body and legs of an 80 yr old, trying to kick the hell out of a grocery store owner who generously acts as though Robert de Niro in Goodfellas is kicking the hell out of him.

Watch ANY other Scorsese film. The Irishman comes nowhere near them in terms of quality. Or if you like characters with slightly non-human faces, maybe Avatar or Anomalisa.
