I'm sure all the Doctor Who fans out there know Karen Gillan very well. She play the character of Amy Pond in the Doctor Who series. One thing about Doctor Who fans is if you really want to upset them, call the main character "Doctor Who." They will flip. "He's not Doctor Who. He is THE DOCTOR!" I'm the same way with anything Star Wars, so I can't really say much.
For American audiences, Karen Gillan broke out in the show 'Selfie' alongside Jonathan Cho. You'd never know she was Irish from that and her most recent work on 'Guardians of the Galaxy' and 'Jumanji,' but she does, in fact, have an accent. That's pretty incredible considering the multitude of voices she's shown between those two movies. Nebula is a very monotone character while her character in 'Jumanji' was like a teen girl.
