Ewan McGregor not recognised by Star Wars fans

Long Way Down started showing on BBC2 last night, Ewan McGregor and Charley Boorman's trip from John O'Groats to Cape Town. I thought it was highly entertaining, enjoyed it a lot. For the Star Wars geeks you also get Ewan doing Luke Skywalker impressions, telling stories about Tunisia and signing some kids Star Wars DVD's.

In an interview about an upcoming episode I heard Ewan say how when they visited the Star Wars set in Tunisia (well, okay, it's a place that the Star Wars films used, Lucasfilm doesn't own it. Yet.). Ewan was a bit worried that he might be mobbed by the Star Wars fan tourists, but wasn't recognised at all. At which point he started wondering why. he tells it better than I do.
