Released in 1993, 'Last Action Hero' was an action-packed, meta-curiosity: a young movie fan is transported into a parallel dimension, where he must work alongside the star of a series of action films to stop the villain of those films when he escapes into the real world. Arnold Schwarzenegger plays a fictional version of himself, the star of the "Jack Slater" series of movies within the movie, which is filled with all sorts of satirical winks and nods to the world of cinema. While the film performed poorly at the box office, it's become something of a cult favorite over time. 20 years later, we take a look back at this truly unique release and see what Schwarzenegger and friends are up to now.
