Just like with THE MUMMY series of classic Universal monster films, I've never been the biggest fan of the original INVISIBLE MAN but I sure do find the sequels goofily entertaining! This one might be the goofiest but also my favorite. You get a nutty professor played by John Barrymore, his maid played by The Wicked Witch of The West herself(Margaret Hamilton) and a tough guy gangster played by that notorious tough guy Shemp of The Three Stooges! Clearly meant as a comedy or spoof this one is a good co-feature with any of the Abbott & Costello monster meeting romps.
There is a 1983 TV-movie with this same title starring Gilligan(Bob Denver) who makes a lady invisible which I think I need to see sometime.
