I'm a long-time fan of Rob Long, and his books are hugely re-readable, detailing the ins and outs of being a Hollywood comedy writer with a past success but with everything to prove.

I think we all have those moments at one point or other in our lives... when we see someone and immediately imagine a whole universe around them. A relationship, a future, and all based on just a second which might not even have been in their company. It's amazing how quickly the human mind can come up with this stuff.

I think if you've got a good idea it will stand out in one of the different mediums. For example, something might happen to me today and it could be something to talk about tomorrow on the radio, or I can write about it, or perhaps it will be best suited to telly.

A man came up to me at a party and asked if I wanted to be in his video game. I of course said yes. And then it turned out it was 'Assassin's Creed', so that was great. They let me ad lib a lot and mess about and be very snarky indeed, and I'm thrilled by the success of all their hard work.
