That's a great idea! All I could find about authorship was in this bit in the Wikipedia entry:

Kazaam is a 1996 American musical fantasy comedy film directed by Paul Michael Glaser, written by Christian Ford and Roger Soffer based on a story by Glaser, and starring Shaquille O'Neal as the title character, a 5,000-year-old genie who appears from a magic boombox to grant a boy three wishes.

Hubs swears he read it in a book and has never watched Kazaam. Ah well!
