He is one of my favorite actors. I read an old Q&A of him and know he doesn't like fans sending fanmails asking autographs, so the only way to get his autograph is in person. Unfortunately, I live in Asia and he's mostly active in Europe or the US. But thank all gods, somehow they brought Aidan to Asia--He was shooting a film in Singapore in February. I googled and found a facebook page hiring extras for the film. The filming date and location were attached.
The problem was I didn't know if Aidan would be there and the page starter didn't reply my mail. I still decided to fly to Singapore to try my luck.
Of course I met Aidan in person! The film crew were very nice and helped me ask Aidan to see me. He was talkative than expected and took his time to pose for me! Walking with him and seeing his facial expressions was so unreal.
I thought everything would be in a rush, but we chatted for about five minutes. 
I brought QAF booklet and his old indie film, one of his favorite work, to be signed.
I notice that the signature is very different from his old ones in some autograph sites!
You can see his other pics I took in my Flickr account
(I'm from Taiwan tho) It may be the nearest place I can see him! 
I'm just a lucky little fan, but I'm happy to fly all this way for Aidan
