I went back over the sketch books I'd filled at Sheffield for ideas and discovered Wallace and Gromit, except Gromit was a cat then. I made them into Plasticene shapes and started 'A Grand Day Out.' It took me longer than I expected.

As I get on and films take four years to complete, I tend to have a hankering for very short projects so you can move on to the next idea. It's the ideas I'm interested in. What comes out of your head.

Startups need to focus on building a foundation for their company culture early, and then they need to revisit it often. Every time a hire is made, a feature is launched, a Facebook status is updated, a press interview is given, a round of financing is raised, or a meeting is held, culture should be part of the decision-making process.
