Howard the Duck (1986)

Visible crew/equipment: When the Overlord is busy destroying the Diner, when he starts destroying stuff on the counter, you can see the small rods pop up that flip the saucers and glasses into the air. You can also see the compressed air they used, to aid with the effect.

Other mistake: In the scene where Howard falls asleep in Beverly's apartment window and his wallet falls out, she takes out the money. The city on the bill says Washington DC instead of Marshington DC. (00:19:00)

Continuity mistake: For a few moments during the flight scene near the end of the film Tim Robbins has no handcuffs on, but they are back on again seconds later.
