Kinda funny, no kind of story, good acting, and the strangest music ever
Somehow I never saw this until 2010! Hero At Large was my 2nd favorite film for many years, and ET was my favorite film when I was a young teen, so it almost seems impossible that I wouldn't see a John Ritter film with aliens in it.
I'm reasonably certain that they started filming without a script and made it up during bathroom breaks, and the onscreen announcements (Las Vegas - Monday) were an afterthought somebody had when editing. Most of it is pretty funny, though, and the acting is very good. Having only seen him in the unwatchable According to Jim, I'd no idea that James Belushi was actually an okay actor.
The locations are the second worst I've seen in my life, second only to Drive on Fox (which was the first worst in all other categories, probably). At least 95% of this was filmed in Canoga Park (L.A.) and downtown L.A., with most of it in Canoga Park. During constant filming in downtown L.A., the words on the screen keep changing, telling us they are in Las Vegas, New Mexico, Indianapolis, etc., when they haven't moved three blocks!
The music is the strangest music I have ever heard in a film---by far! Most of it is a strange superimposition of one style over another, totally different style. For example, a really smooth soulful rhythm track that sounds like Shaft or Barney Miller will have a gypsy violin over it, and maybe some country picking, then the meter changes to the style of an oom pah pah band, but it still has the instruments from the smooth soulful rhythm track. Early on, it is just traditional movie score music, but very, very overly melodramatic (i.e., the Gone With the Wind orchestra style while they are in a suburban home). All the rest of it is a wildly eclectic mash-up of incompatible styles.
If you can see it for free, do it, you'll have fun.
This movie really missed the mark, but I'll say this:
If this movie had been twice as bad, it would be a runaway cult classic with kids dropping acid and laughing their asses off at midnight showings.
