I've never really understood the problems he had getting the Hitchhiker movie made - all the articles around before it came out talked about having to revise the script to make sense to an American audience (and the eventual movie ended up with a strangely different plot with a villain), but the original radio series is pretty much a road movie, which is almost an American trope.

Adams himself changed the plot in every version of HHGG, from radio play to book to computer game to movie. I think it shows how little he was attached to the details of his fictional universe. Personally, I like the plot of the movie a lot, especially the invention of the point-of-view gun

I think the special effects were a problem at the time - Zaphod's heads never really looked good.
