This one is NOT a sequel to The Invisible Man Returns. In fact, there's not a moment of horror or thriller in it. This does not mean it's a bad film. In fact, it's quite excellent. The Invisible Woman can best be described as a romantic comedy with touches of Sci-Fi for good measure. The case includes the legendary John Barymore [Dr. Jekyll and Mr. Hyde, 1920, a brilliant performance] as Professor Gibbs who invents an invisibility machine. This was one of his last onscreen roles and he is still in top form here. The one and only Margaret Hamilton [The Wicked Witch in the Wizard of Oz] is one of his faithful servants. Her mere presence makes me smile with delight.
The Invisible Woman is played with wit and charm by Virginia Bruce who uses her invisibility to take revenge on the men who have done her wrong. She settles the score, not with murder, but with humor and ridicule. It's a fun role and she seems to be having a great time with it.
The screenplay was written by Curt Siodmak and Joe May who also collaborated on The Invisible Man Returns. They really know how to write a good script and this one is no exception. The director this time out is not May but A. Edward Sutherland who definitely knows how to pace 1940's comedies. He keeps things light and fast which works well.
If you're looking for the Invisible Woman to have a tortured evil soul, you'll have to look elsewhere. If you like those "battle of the sexes" comedies of the 40's and 50's then this one will fit the bill nicely. Just remember, this is NOT a horror film.
