George and the Dragon (2004)
The relationship and background of George and Tarik is taken from that of Robin and Azeem in Robin Hood: Prince of Thieves (1991).
The giant reptile feces.
The line "George! Watch out for the trees!" as George is about to collide with a tree.
In one scene, Tarik wears a black suit of armor plus full helmet and imitates Darth Vader's breathing.
