Did you know...
That Diego was supposed to die in the first movie?
That's how it was in the original script, but Dennis Leary said the kids wouldn't like that. The creators agreed so they changed the script.
What would you think the filmes would be like if Diego was killed in the the 1st one? They'd definitely be very different... and in my opinion, not as fun, because Diego is my favorito character (along with Sid and Buck, but that's a different story).
