Set identification - Movie set
There are multiple sets indeed.

First and last minifigures are part of 1356 Stuntman Catapult set. Stuntman is unique to this set.



Looks like the second and third minifigures, camera as well as most of the parts are from 1355 Temple of Gloom



This leaves us with some bits as well as last minifigure - fourth from left is Baron Von Barron with Pith Helmet and White Epaulettes, also appears in 11 sets. This minifigure as well as baby dinosaur, including some leftovers after first two sets indicate these could be from 5914 Baby T-Rex Trap.
