Sci-fi movies often contain their fair share of action, so its no surprise that plenty of action movie heroes have appeared in some fantastically strange science-fiction films. The nature of sci-fi stories means they embrace unbelievable concepts and tap into innate human fears around technology and progress. While this can lead to some undeniable movie classics, it also means that major box office stars sometimes end up participating in movies that were just downright strange and destined to become beloved cult classics or, in other instances, reviled box office bombs.
