The Black Swan star admits she even visited the Star Trek Experience exhibit in Las Vegas - and hung out with other superfans.
She tells GQ magazine, "I got into it in my late teens - 18, 19, 20. Something like that. I got into it later than most people, but let’s not talk about it in the past tense - I'm still a Star Trek fan. You never stop being one.
"I went to the Star Trek Experience in Vegas maybe five years ago. I hung out with a bunch of fake characters inside Quark’s bar. There were all these actors there pretending to be the different characters from the different shows... I loved it."
And she has one memento many Star Trek fans would kill for - Leonard Nimoy’s autograph.
