I can't get my head around the fact that the technology of the first two movies, which are forty years prior to Star Wars, is so much better than any technology they had in Star Wars!

The attraction, and my particular participation is in being able to communicate with my fans, answer their questions, get a feel for how they respond to Vader.

I'm also involved in the rights of the disabled and do some fundraising for that and I thought it would have been a big boost for the campaign but it couldn't be worked out.

I'd worked in Clockwork Orange with Stanley Kubrick and since Stanley was such a prestigious director this opened all sorts of doors for me - one of them being Star Wars.

I am doing better now though one of my legs is shorter than the other due to the operations.

I do remember smiling quite a bit inside it though since I knew it wouldn't be seen on film - so of course while the poor planet is being blown up I'm smiling and laughing like mad!

But I must say the work I'm proudest of is the Green Cross Code man.
