Skyfall

Whilst inbetween careers I signed up to be an extra, it was a bit embarrassing and I got two jobs out of it, one was to be in the background of a dating advert filmed at the V&A and the other was to be in Skyfall. So I spent a few days knocking around on set being all bewildered. One the last day I got put in a really visible chair in the scene where Q gets hacked. Some extras spend lives waiting for gig that sweet. I retired straight after.

Kevin McCloud

In 2008 (when I was a mildly successful comedian) Radio 4 commissioned me to do a story show. I wrote Dad Designs all about how I didn’t much like my dad and that given the choice I’d pick Kevin McCloud from Grand Designs as my ideal dad.

I was expecting to get an actor to play him because of course the real McCloud wouldn't be interested, but by an old boy network twist of fate he had gone to uni with the head of BBC comedy, so he agreed to be in it. Weird.

Barack Obama

He follows me on twitter, can't remember why exactly. I think it was back before he was famous (and a president) and when twitter was young and this senator said ‘Follow me and I’ll follow you’. I did, he did, still does!
