In the scene where Indy is about to drop down into the Well of the Souls, Sullah says to him "Asps, very dangerous..." O.K, let's analyze the snakes in the pit. The first is obvious, it's not an Asp, but a Cobra (I'll let that one slide). After they pan across the floor, you see snakes from South America, Australia, North America and other locales. How, exactly, did a common Boa Constrictor from South America end up in a pit in Egypt? A less serious slip up is at the very beginning when Indy jumps into the plane with Jock and is greeted by his pet snake "Reggie". I find it hard to believe that Jock traveled all the way to South America with an Asian species of Python.
