In My Stepmother Is an Alien (1988), the piano on Celeste’s spaceship in the end credits is played by Jon Lovitz (who plays Ron Mills in the film).

Quick Scoop

  • Film : My Stepmother Is an Alien (1988)
  • Director : Richard Benjamin
  • Main cast : Dan Aykroyd, Kim Basinger, Jon Lovitz, Alyson Hannigan
  • Piano scene : End credits bonus scene on the spaceship, featuring Jon Lovitz at the piano.

Who’s Actually Playing the Piano?

The “piano player” in the movie itself (during the main story) is not a named character or a guest musician; the notable piano moment is a crazy credits gag :

  • In the end credits, there’s an extra scene showing:
    • Jessie (Alyson Hannigan) playing basketball with her family.
    • Jon Lovitz on Celeste’s spaceship, playing the piano surrounded by members of the 12th Navigational Command.

So:

  • As a character in the film: Jon Lovitz (Ron Mills) is the one shown playing the piano in that spaceship gag.
  • There is no separate, credited “pianist” character for the story; the piano moment is purely a humorous end-credits flourish.

Why This Gets Asked

People often remember:

  • The quirky spaceship scene.
  • Jon Lovitz’s funny, over-the-top performance style.
  • The oddness of seeing him “playing piano” with alien crew members around him.

That combination makes it a small but memorable detail that fans associate with the film’s comedy vibe in the late-80s sci-fi/romance setting.
