I personally think this one's fake...

 

the last 2 do look quite fake...

 

Not with pics but on 'Hellboy'

When in the museum Hellboy loads the gun with 4 rounds but fires 5

Then when he gets run over by the train and touches his horns he says ow, but he is fireproof and grinds them down himself.

 

 

I notice these goofs all the time

 

Have you seen the sexual inuidos in Disney movies, the erection of the priest in the Little Mermaid, the one on the castle too. I think the animators make these as a joke in a single frame and there is some weird extreme group who watches kids movies to find these flaws,
by the wa,y the Johnny Depp photo looks really really fake
