The most useful form of time travel would be to go back a year or two and rectify the mistakes we made.

It's important to hold something back, though, because quite frankly my personal life is pretty dull and I don't want to bore people with it.

My favourite song of Elton's is... it's a tricky one for me. I'm a proper fan and I've probably seen him in concert about a dozen times before I even met him. Mona Lisas and Mad Hatters, which isn't in this film... but whenever I see him, I always tell him that Passengers is my favourite song because it's one of his least auspicious ones.

But we did see the process develop. I remember going to the Rocket Pictures base and they had something like 40 people there, drawing. They didn't know what the characters looked like yet and I remember on the walls seeing 30 or 40 different versions of Juliet. So, it was then that I realised that someone's got to come in and make some really executive decisions.

Keep yourself busy if you want to avoid depression. For me, inactivity is the enemy.

I mean comedy is something that's very personal and people have strong opinions about.

I think this [Gnomeo & Juliet] is the closest I ought to get to Shakespeare to be honest.
