It's a shame, but every time I get something scientific in the script, I read up to find out what I'm talking about - but then I'm on to the next script and it's forgotten.

I grew up with two different parakeets - one that lived for five years, and one that lived for 13 years - so I always had a bit of an attraction to birds and it's an oddly good fit to be in a movie about birdwatchers.

Realistically, there is a danger, of course, when you're going into someone's living room as the same guy every week. But I don't fear it because, I mean, there's really nothing I can do about it. I can try to combat it through the work, and maybe make sure I don't do Sheldon 2.0 in any other projects. But it's just really hard for me to find any negative side effects from this experience.

It was just wet, not stinky?

As a human being, you know that there are some days when you'd rather not talk to anybody - but I can't really do that anymore without appearing rude.

My choices in projects have all been character or role-based, and on a financial level, it's obvious: as an actor on a TV series, I get a wonderful paycheck, and a consistent paycheck, which doesn't always happen when you're doing theater or movies.

I didn't have an imaginary childhood friend, but I did one day imagine somehow tiny green men, and they were only tiny and green because my brother had a ton of toy soldier toys that came on a skateboard plank type of thing, and I just envisioned in this car driving to church with my mom, they were there.
