Visible crew/equipment: Near the end of the movie, before they turn into wolves, you can see the reflection of the crew in the window.

The Wolfman (2010)
1 visible crew/equipment mistake - chronological order
Starring: Anthony Hopkins, Emily Blunt, Benicio Del Toro, Hugo Weaving
Other mistake: When Lawrence is looking at his wound in the mirror, it has slightly healed. Later, when Sir John visits Lawrence in the asylum, he shows the bite mark he got from the feral child to Lawrence. Since Sir John is also a werewolf, the bite mark should not be there.
Sir John Talbot: I don't think they'll kill you, Lawrence. But they will blame you. The beast will have its day. The beast will out.
Trivia: Maybe more coincidence than trivia, but towards the end of the film, Gwen shoots and kills the Wolfman/Lawrence Talbot - in effect, beauty kills the beast. In Universal Studios' other major classic monster movie, King Kong, the beauty kills the big ape, albeit indirectly.
