a dog is in very minor danger for a short moment but is not injured and is completely fine (an egg is thrown at someone holding a dog, it’s really not a huge amount of danger)
there is a part where there is a competition between two of the main characters that involves removing their underwear, but nothing is shown and they aren't soiled
no but there might be black face. it’s not a racial caricature but a white man covers his face in coal dust to scare someone. later, it’s implied that characters use race face to sneak into somewhere; however, they are represented by actors of color and the original actors voices are dubbed in
Zoolander and Owen Wilson’s character use race-face to disguise themselves as POC working at Mugatu’s event to sneak into it. They’re physically portrayed by nonwhite actors in this scene IIRC but their voices are the same. Gag where Zoolander is covered in coal dust and made to look like blackface.
