I thought Airplane II: The Sequel was a ZAZ movie, then I go on here and find out some Ken guy made this movie! They sure fooled me! Oh well, it's still very funny. I just hope that eventually ZAZ decides to make Airplane III.
But then I think I personally would have taken steps to make sure she didn't grow up to be a prostitute. They washed their hands of her, they can't complain about what she became. If they didn't want to risk a sequel they should have tried to keep the rights. They didn't keep the rights, and they were offered the sequel and turned it down, that to me says they have nothing to complain about.
The sequel was good though so hopefully one day they will appreciate that the crew that took over actually made a pretty decent job of it.
Acutally on the AIRPLANE 1 Commentary they mention that they exhaused all their jokes about "disaster on a plane" so they didn't have any real ideas for a sequal.
I think they kept making NAKED GUN sequals because they put a lot of different parodies in those films and not just about old cop shows and detective movies. The A.P. movie was all the "plane" disaster movies they could do joke about I guess.
