In a scene a boy (Nathan Forrest Winters, 13) walks around in only pajama bottoms, then wets his bed when frightened by a dream. In the morning his butt is seen as he pulls on dry underwear.
Honza (Jan Morávek, 11 or his twin brother Martin Morávek) and his friends are watching nude women in the bath house and have to run away naked: brief frontal nudity. Nude girl (8?) opens them a door.
