The Invisible Ray is a 1936 American science-fiction horror film directed by Lambert Hillyer. It stars Boris Karloff as Dr. Janos Rukh, a scientist who comes in contact with a meteorite composed of an element known as "Radium X". After exposure to its rays begins to make him glow in the dark, his touch becomes deadly, and he begins to be slowly driven mad. Alongside Karloff, the film's cast includes Bela Lugosi, Frances Drake, Frank Lawton, Walter Kingsford, Beulah Bondi, Violet Kemble Cooper, and Nydia Westman.

Beulah Bondi was an American character actress; she often played eccentric mothers and later grandmothers and wives, although she was known for numerous other roles. She began her acting career as a young child in theater, and after establishing herself as a Broadway stage actress in 1925, she reprised her role in Street Scene for the 1931 film version.
