Start with a knockoff of "The Fly" with the setting changed from Montreal to London (England, not Ontario) with added elements of "Darkman" (though that movie was still more than 20 years in the future). Add liberal amounts of nondescript English actors, add an officious bureaucrat who looks like G.I. Joe (the one with the fuzzy hair and beard) and a cute young blonde who spends much of the movie in her underwear. Fold in lots and lots and lots of talking and top off with Bryant Halliday in some pretty cool monster makeup, and you have this movie.
Was it any good? Well, it was OK, but a movie like this seems like it should have been much more interesting. David Cronenberg could have done this much better. Heck, Freddie Francis could have done this movie better....
