In a new interview with The Wall Street Journal Eddie Redmayne discusses his role as Newt Scamander in Fantastic Beasts & Where To Find Them.

Is “Fantastic Beasts” easier to play, without all the physical changes?

I think it may just be my personality, but I always find a reason to worry. So with Stephen Hawking it was about letting down Stephen. With Lili’s story it’s about letting down the trans community. And with “Fantastic Beasts” it’s wanting to do justice to an extraordinary world that J.K. Rowling has created.

Do you have to deal with any live animals or just imaginary creatures?

There are some live animals. Dan Fogler [who plays Newt’s nonwizard friend] and I had to negotiate quite some epically-sized snakes the other day. We went, “Wait a second, can’t we CGI those in?”

Eddie’s newest film, The Danish Girl, will be released on November 27th.
