Revealing mistake: The chimpanzee, Jebo, is wearing a dress and imitating dancing in one scene. As Jebo runs off, Jane exclaims "My dress.". There is NO WAY that dress could have fitted a grown woman. It is a pretty nice fit for the much smaller monkey, though.
Tarzan and the Lost City (1998)
1 revealing mistake - chronological order
Directed by: Carl Schenkel
Starring: Casper Van Dien, Steven Waddington, Jane March, Winston Ntshona
Visible crew/equipment: Just after Tarzan goes under the stone door, he finds the torches dropped by the bad guys. The flame from one of the torches is reflected in the camera lens, and was caught on tape. It looks like a single, unattached flame is hovering on the stone wall nearby. This is made even better when Tarzan picks up the torch and then drops it, the reflection follows his movements precisely.
