That's Entertainment?

I know I've never seen any of the various "Airport" (or other movies featuring air-disasters) on any flights during all my years of flying. And, on commuter rail (metroliners, regionals or Acela-type), I've never noticed a video option available (though, on an Acela trip back from NYC, I watched Midnight Meat Train on my laptop). Do they ever show "Poseidon Adventure" or "Titanic" on cruise ships' in-room movies?
