The Vanishing Shadow is a 1934 Universal science fiction film serial directed by Lew Landers.

Many science fiction gadgets, including a robot and The Destroying Ray, are also featured in the serial.

Stanley Stanfield is the inventor of the Vanishing Ray, a wearable device which, when active, leaves only the user's shadow still visible.

After meeting with fellow scientist, Carl Van Dorn, a prototype Ray is built.
