There are things that are a given, that you've already established, and obviously, visually, certain iconic things that can't be completely removed, like a certain hat or a certain coat in my case.

Every job is incredibly different, and I love it because you're picking up skill sets and experiences. It's the university of life.

Even though my parents experiences were different from mine. I wasn't a child actor brat; I didn't travel with them in the circuit. But I got a look into their world, so I did know what I was getting into, to an extent. And they are a constant source of grounding.

I tend to have a cup of tea, try to stop worrying about what I did wrong, cool down and will the audience back in as soon as possible.

The generation now below me were born into a world where if you're a kid with raw talent now, you can roll in and land a lead in a Scorsese film. You don't have to have prove yourself by working up the ranks, doing the classics, and getting the canon under your belt in the way the great Sirs and Dames of mom and dad's generation - the [Ben] Kingsleys and [Helen] Mirrens and [Anthony] Hopkinses and people of that ilk.

What's not to look forward to? It's like all the actors in all of the films. It's difficult to get Martin Freeman and I in a room together. Imagine what it's like to get myself, Chris Hemsworth, Robert Downey Jr., Elizabeth Olsen... these extraordinary actors who all have careers outside the Marvel Universe.

I'm really not Sherlock Holmes. I look a little bit like him and sound like him.
