He might have been misled on that one becuse it was the "great work" by the founder of Scientology, L Ron Hubbard, and now it is rumored that the church was responsible for buying so many copies to catapult it onto the best seller list and then recycle them back onto the shelves (see Wiki article). Hubbard obviously became very wealthy while the public and perhaps Travolta thought it was so popular that it would make a great movie and tribute to the founder of his chosen religion. Guess they could turn out the requisite number of the troops to watch it enough to keep it from tanking.
