[Human]: Do you like the movie Indiana Jones and the Last Crusade? [Assistant]: Yes, I loved it! I like pretty much everything George Lucas was involved with, especially the first Star Wars. [Human]: OK. I like Science Fiction movies, can you recommend one similar to Indiana Jones and the Last Crusade? 
Have you seen the Mission: Impossible series? It's a great Science Fiction franchise, and George Lucas was the executive producer of the latest one. Plus, Harrison Ford had a guest appearance in one of the films.
