Corrected entry: During the Kappa fight scene, the Kappa tries to steal the Sword of Storms from Hellboy. Hellboy grabs the sword by the blade and yanks it back, implying the blade must be quite dull, or else it would easilly cut his hand very deeply. However, later in the film, it is shown the sword is in fact quite sharp, able to sever the limbs of a giant Oni-like demon, thus meaning Hellboy should not have been able to grab it unprotected with his bare hand as he did earlier.

Factual error: When Liz and Abe's plane crashes, it sinks far too quickly to be realistic. Also, from the sheer amount of force the plane hit the water with, both should easily have died. Obviously done for dramatic effect, but still a mistake.
Trivia: The scene where Hellboy battles the vampiric heads is taken directly from one of the stories from the comic book, entitled "Heads." It was faithfully recreated when Mike Mignola and the writers realized that the story would be perfect for the semi-episodic nature of the film, and the Japanese-themed tone.
Correction: He actually grabs it with his stone hand, not his flesh-hand, so it makes sense the damage is minimal.
