Deliberate mistake: In the final battle at the end, Mark Loftmore enters the back room where we see Mr. Lincoln leaning over the body of an older man with a red jacket whom Lincoln has apparently just shot. This same man later appears in the background of at least one shot of the general melee taking place outside in the gallery.
Waxwork (1988)
1 deliberate mistake
Directed by: Anthony Hickox
Starring: Deborah Foreman, Zach Galligan, Jennifer Bassey, Joe Baker
Revealing mistake: When they are observing the waxwork figures, it's obvious they are real people just trying to stand still, as you can easily notice the "wax" figures slightly rocking or moving, or the props they are holding doing the same.
Mr. Lincoln: They'll make a movie about anything nowadays.
