I drive a motorbike, so there is the whiff of the grim reaper round every corner, especially in London.

As an actor, you are aware of how a role can seep into your real life.

I was very keen to work on the script with Scott Derrickson and [C. Robert] Cargill, and working out the important story beats, changing lines, upping the comedy, changing the pace, all of that was great fun.

Actor is an odd profession, and sometimes people get jealous, but I haven't really experienced any of that. Everyone's been really happy for me, which is really, really great.

It does get strange when you realize people will hang around for hours to get a glimpse of you doing scenes outside.

I always get self-conscious about what I look like in a film, but less so if I'm a character very far removed from who I am. Then I just worry about the performance, and that's equally an odd experience.

It's always important to have the blessing.
