Invisible Invaders is a 1959 science fiction film starring John Agar, Jean Byron, John Carradine and Philip Tonge. It was produced by Robert E. Kent, directed by Edward L. Cahn and written by Samuel Newman. The monster costume from 1958's It! The Terror from Beyond Space was reused in this film (purposely blurred a bit by the cameraman) to represent the invisible alien who briefly turns visible just at the point of dying.
