Karen Gillan details 'big girlie fight sequence' with Zoe Saldana in 'Guardians of the Galaxy,' talks bald head [VIDEO]

In a new interview with MTV News, Karen Gillan revealed some fun details about Guardians of the Galaxy and her character Nebula. The Oculus star spoke about her shaved head making her feel naked, her character's drive, and fighting Zoe Saldana.

"Yeah, there's a big girlie fight sequence, but it's not that girlie. They made sure there weren't any nice pirouettes or anything like that," the former Doctor Who companion said. "[Saldana is] really experienced in the physical stuff, she was a ballerina. She's really amazing at all of that stuff. She barely required any rehearsal, she was like, 'I can do this.' I required two months of rehearsals every day that I wasn't shooting, because I looked like spaghetti when I started."

She added: "This is the integral one for my character, because it's not just a physical battle. Their relationship goes very deep, and there's a huge history between them. So there's a lot more to it than just the physical."

In order to truly get into character, Karen shaved off her luscious red hair, thus sending the Internet into a frenzy. But what how did it affect her?

"It was the saddest thing in the world," Gillan said. "They'd use a big industrial wind machine when filming [Zoe], but when it was on me, it was like, 'Turn the wind machine off,' and it was like beeeeup."
