In the first 10 minutes when the boy Ravenfeather (Vaclav Tvaroh, 9) only wears a loose loincloth. It fails to cover anything when he's struggling or carried by someone, front and rear briefly seen a few times.
Christian Slater (17) is pretty creepy as an evil youngster who begins terrorising his babysitter. In one scene he is taunting her with a kitten. She grabs for it, but he spins and she pulls his trousers down instead. We see his rear for a couple of seconds, as he stands up and does his trousers back up.
