Siegfried is shirtless for the first 36 minutes of the film. During this time, after the dragon sequence, he is briefly seen bathing naked from a distance. It is extremely brief and indistinct, but his butt is visible.

Besides that there is no nudity.

There is some killing, as one might expect in a heroic tale, but it is not gory.

None.

Siegfried drinks wine and at one point expresses a desire for wine.
