2. 'Star Trek IV: Voyage Home'
Gene Roddenberry had a vision for a Star Trek movie he never tired of sharing: the gang travels back in time to Dallas in 1963 to prevent the assassination of JFK, but Spock winds up becoming the second gunman on the grassy knoll in order to preserve the original timeline. That movie never got made, but when it came time for a fourth Star Trek movie, he was able to see them travel back in time to 1986 in order to bring a couple of humpback whales back to their own time in order to save the planet from a hostile alien probe. That all sounds very complicated, but it's all just an excuse to put the characters into 1980s San Francisco and let the jokes fly. This was a Star Trek movie that could be enjoyed by people that hadn't seen a second of the TV series or the previous films, and audiences ate it up. It grossed $133 million and played on cable for years. Star Trek was never quite this funny and light ever again.
