I can answer in one sentence: I have been trooping in costume at the opening of a Star Wars The Exhibition, with Anthony Daniels.

I got a few days access to the exhibit, which was nice. Building prop replicas is one of my hobbies. Unfortunately, there weren't too many props from the OT, but I still filled the small memory card on the camera.

You can sometimes meet some actor or some unknown extra at sci-fi conventions, and get his/her autograph for a fee... I have seen David Prowse (who wore the Darth Vader suit) more times than I can count -- signing autographs seems to be the only thing he does for a living. So far, I have got nineteen autographs from actors in the OT on a couple of posters, but I am still missing a few that I really want: "the three", Kenneth Colley (Piett) and Denis Lawson. Harrison Ford and Denis Lawson are known to wanting to distance themselves from Star Wars and they almost never write autographs.
