Ula references that she and Bialystock "go to hotel".

Bialystock plays non-explicit fully clothed role-playing games with a myriad of "little old ladies" for money. It is never mentioned whether he sleeps with them or not.

A building blows up, characters are later seen in casts.

A character fires a gun several times at other people.

A character is comically hit on the head with a wrench.

A character has an over the top panic attack and is egged on by his antagonist (non-violent).

The main characters smoke cigars and drink champagne in celebration. At a bar, the characters meet a "cheerful" drunk who sings songs and acts silly.

The Hitler/WWII references will probably go over younger viewers heads. Nothing really frightening/intense in the film as everything is done comically.
