Claude Rains may have meddled in things that Man must leave alone, but that doesn't mean Woman shouldn't get in on the act. Kitty Carroll (Virginia Bruce) answers an ad in the paper to be an experimental subject for John Barrymore's dauntingly daffy Professor Gibbs, whose invisibility serum, if successful, promises to replenish the dwindling fortune of his benefactor, Dick Russell (John Howard) - if only he can get a human subject. Kitty's aim, however, is to wreak havoc on the draconian boss of her modelling job, the aptly named Mr Growley (Charles Lane).

When it was released during Hollywood's golden year of 1939, The Wizard of Oz didn't start out as the perennial classic it has since become. The film did respectable business, but it wasn't until its debut on television that this family favorite saw its popularity soar. And while Oz's TV broadcasts are now controlled by media mogul Ted Turner (who owns the rights), the advent of home video has made this lively musical a mainstay in the staple diet of great American films.
