When the Winnebago is escaping from the ship, the princess exclaims something like, "There's the end!" But when the passengers' point of view is shown again, the end of the tunnel is not visible yet.
Ya, I noticed this too. I didn't really think anything of it though b/c the movie is so stupid/funny anyways. But, you are right, you can't see the end on radar or out of the front window.....oh well...laugh on!
HELLO??!?!?!?! It's a spoof movie!! Can't you see they're making fun of all those movies that do things like that?!?!?! For example, take into account the fact that nobody in this movie gets hit by a laser blast except Vespa. It's like Star Wars!!!!
