If you watch the bit where the Hulk throws something through the window to escape it actually hits him before he makes his escape. Watch it and you will see this was not suppose to happen. Quite amusing though.
When David and the girl are in the jeep, Little Jim refers to David as "White Eyes" - Which is an obvious reference to his transformation into the hulk. A nice little in joke.
Lone Wolf: (re prehistoric Hulk) He is father to demons, and to all people. The first hunter. He walks the land, eliminating the boundaries and making us all one great tribe.
Michael: Why is he green, grandfather?
Lone Wolf: To overcome the hatred. If he were yellow, or brown, or red like us, or even white - any of the colours of man - whichever he was, that people would think they were superior. So he is green. The only one, and that makes the rest of us the same.
Lone Wolf: (to Jack McGee) He'll wander the land until his burial ground is restored.
Gabrielle: I knew who you were when we met at the museum.
David: I could say that you're mistaken.
Prof. Williams: (to David, after the latter is quickly hired by Gabrielle) Indecision. The privilege of the young.
Reporter: (to Professor Williams) Isn't the missing link as big a myth as the Hulk? Or should I say as big a hoax?
Reporter: Well, no doubt about it. Famous Professor Williams has been in the desert sun once too often.
Jack McGee: What he saw was the Hulk. And the only missing link is the name of the man who becomes the Hulk!
Reporter: You're crazy, McGee. He's senile. You're crazy!
(Jack McGee enters Gabrielle's lab, asking to speak to Professor Williams)
Gabrielle: He's not seeing any reporters, especially you.
Jack McGee: Oh, especially me? Since when did I get to be the bad guy?
Gabrielle: It probably has something to do with your paper's reputation.
Michael: Giant and green! Honest!
Jack McGee: Oh, I believe you.
Michael: You do?

The hypothetical gamma radiation explosion that David thinks created the prehistoric Hulk may be an allusion to the gamma bomb explosion that created the comic book Hulk.
