Factual error: A theater marquee is visible promoting the showing of a film called Tribeca Follies. The acronym "Tribeca" - an amalgamation of "Triangle Below Canal [Street]" - didn't come into usage until the 1970s.
Factual error: In the beginning of the film, the Dowager Empress Marie states that the year is 1916 and that they are celebrating the 300th anniversary of their family's rule. The 300th anniversary actually took place in 1913. (00:01:05)
Continuity mistake: When Elton and John Reid are kissing in the cupboard John's hand keeps changing between shots. John's hand rolls down Elton's chest, then the next shot it's on Elton's cheek, the next shot he takes his hand away, then the next shot his hand is by Elton's mouth and Elton pretends to bite John's thumb.
Revealing mistake: After Nuclear Man destroys the cab's hood, the shot changes and there's a thick string running behind him all along the car, and the cab driver is stretching out to pull it. Probably he was activating some sort of bad FX.
Plot hole: So he needed the help of a big strong burly guy to flip the safe with the body, end over end to the pit, but he somehow was able to easily get it out of his basement and into the back of his car by himself?
Continuity mistake: When Hellboy is walking at one point, holding his gun up in his left, gloved hand (just after one of the agents has said "This place is like swiss cheese"), watch the frame.

Continuity mistake: In the scene where they are in the all you can eat restaurant, when PaPa Klump farts into the candle causing the curtain to catch fire, when they first show the curtain after the 2 men put out the fire, there is clearly a burn mark on the edge of the curtain. However, when they show the curtain again, there is no burn mark. (00:17:25)
Visible crew/equipment: In a scene in a cave that is the lair of the "eaters of the dead," the camera takes an overhead wide angle shot of the "eaters" walking down into the cave. It is possible to see a young man wearing a burgundy t-shirt and beige shorts (a crew member), sitting against the wall of the cave cross-legged. (01:16:55)
Suggested correction: I've watched this scene a number of times on YouTube and I'm certain that this "crew member" is an extra. He is not wearing a T-shirt and shorts, his clothing is correct for an extra. There are also other extras sat cross-legged a few feet from him.
Continuity mistake: Before killing the dragon, Baby Doll is holding her sword with her right hand. But when she jumps up and kills the dragon she is suddenly holding it with her left hand.

Continuity mistake: When Elliot's the basketball player, when he scores the slam-dunk and breaks the headboard, he breaks the headboard after the slam as he bounces/hangs off the headboard.

Plot hole: When Elizabeth is interviewing Victoria for the first time, she mentions that Victoria had sent her an application, therefore her name had to have been on it. However, Maggie Evans didn't change her name to Victoria Winters until she was on the train en route to Collinwood for the interview, therefore Elizabeth would have been expecting Maggie Evans, not Victoria Winters.
Continuity mistake: When Constantine manages to get the mirror through the window he falls on his back. To the right on the screen a chair lies on the floor beside a dresser. A few shots later when it cuts to Constantine getting up we can see the chair has changed position as its back now covers the opening of the dresser. (00:08:15)
Visible crew/equipment: When Lois pulls up to the house where the blackout was traced to, she hears some music coming from the boat down at the dock. As the camera pans upwards over the car, as she steps out, the whole camera and a crew member are reflected in the side of the car.
