Visit where Hollywood makes movies and TV shows, Not to mention all those episodes of the X-Files: http://x-tour.com/. Be sure to go by cancer man's acting studio, and note all those places where the Highlander did his swordfights.
Boyd does a great tour, and he will show you Agent Scully's apartment (Pendrell Suites), also used in a recent episode, "Chocolate"," in Masters of Horror. The back of the place was used in "Romeo Must Die" to depict an Oakland location. Now if I can only talk Boyd into doing an Outer Limits tour.
