Parents guide

Only scene that is sexually explicit is near the beginning of the movie when a man and woman are shown thrusting under covers and moving around intensely. The woman then gets on top of the man and starts to slowly thrust and goes faster and faster while moaning. Although it is not graphic there is a lot of explicit implication

There are some crude jokes

Since it's a mobster movie, there are a lot of bullets, but very little blood is shown (5 deaths are shown).

Some past violence is discussed.

Comic rough-housing including Billy Crystal getting thrown in a shark tank.

85 uses of "f*ck" and its variants, 24 uses of "shit", & a few uses of "pr*ck", with other infrequent profanities scattered in between.

A lot of references, but practically nothing shown.

De Niro's character is very intense and quite threatening.

Not really any
