Based on Richard Matheson's 1963 episode, Australian film-maker George Miller's masterful Nightmare at 20,000 Feet is a hideously stylish, gut-clenchingly horrifying Twilight Zone movie segment, featuring an outstanding central performance by John Lithgow.
"While flying through a violent thunderstorm, airline passenger John Valentine is in an airplane lavatory as he tries to recover from a panic attack. The flight attendants coax Valentine from the lavatory and back to his seat. Valentine notices a hideous gremlin on the wing of the plane and begins to spiral into another severe panic. He watches as the creature wreaks havoc on the wing, damaging the plane's engine." Wikipedia
