Karen Gillan is well known for her role on the British TV series Doctor Who and when she showed up to the San Diego Comic Con, she shocked both Doctor Who fans as well as fans of her upcoming film Guardians of the Galaxy.

The actress was looking as normal as ever, sporting her iconic dark red hair at the panel for Marvel’s Guardians of the Galaxy. Gillan will be portraying Nebula in the film, a villainous space pirate. When it came time for Gillan to speak at the panel, Chris Hardwick jumped in to ask, “Isn’t Nebula bald?”

“Yeah, she is,” Gillan responded. “And I might have done something a little bit crazy.” She then proceeded to whip off her wig to reveal her bald head underneath, shocking and exciting fans according to NY Daily News.

Comic Con got a first glimpse at what’s to come in the movie even though the film has only been filming for a few weeks now. It was only fitting considering the fact that at last year’s Comic Con it was announced that Guardians of the Galaxy would be made into a film reports Slash Film.

The film is set to be released in 2014.
