For whatever reason, Man With Two Lives feels like it's been done before and done better. It is totally predictable until the end of the film where the "surprise" ending is groan-worthy and very cliche. This is not to say it's a bad film. It's simply uninspired as it deals with the theme of the "transmigration of the soul," meaning, the soul keeps coming back and inhabiting other bodies over time.
I won't bore you with all the ho-hum details. It involves a mad scientist, an executed criminal and a man engaged to be married who is killed in a car crash. You can figure it out from there! The acting is fine but really nothing special. Edward Norris does a nice job as Philip Bennett. It's just that he needs better material to work with.
If the subject matter interests you, I suggest you try The Man Who Changed His Mind (1936) starring Boris Karloff. It's a better film. You can download this one for free on Archive.org if you decide to explore this film further.
