Continuity mistake: When Mel Gibson and Robert Downey Jr. are hanging upside down in the copter, the first scene (with the necklace mistake) has Mel in the right seat and Robert in the left seat. When they crash out of the window Mel falls out first from the left seat and then Robert from the right seat.
Continuity mistake: In the jungle, when Mel Gibson and Robert Downey Jr are falling on the ground after jumping out of the helicopter there is a green mat on the ground for them to fall on. The plants on the ground didn't cover it all the way.
Continuity mistake: When Billy was dangling from the rope he was wearing a dressing gown and long sleeved top. When he steps out of the helicopter at the base he is no longer in dressing gown and now has short sleeved t- shirt on.
