"Movies I can't stop watching no matter what point I start watching them."

Are there movies where you could walk by a room where they're being played and be completely sucked into watching them all the way through no matter how much of them you missed already?

These are mine..

  • Aliens
  • Back to the Future
  • The Big Lebowski
  • Braveheart
  • The Departed
  • Grandma's Boy
  • Heat
  • The Hunt for Red October
  • Iron Man
  • Oblivion
  • Top Gun
  • TRON: Legacy
