"Star Trek Into Darkness" opens in theaters this weekend and diehard Trekkies won't be the only ones heading out to see the new J.J. Abrams directed film.
A few of Hollywood's biggest names attend "Star Trek" conventions, have autographed memorabilia from Leonard Nimoy, and even speak Klingon.
If you think you're a huge fan, celebrities from Maria Menounos to Mila Kunis may have you beat.
Mila Kunis has been a Trekkie since her teens.
Kunis told GQ in 2011 she has vintage "Star Trek" figures and a signed photo from Leonard Nimoy.
She's even attended a Trek conference.
"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. [Ed note: Quark was the name of the Ferengi bartender on DS9.] There were all these actors there pretending to be the different characters from the different shows. Yes, I loved it."
Her favorite series? "The Next Generation."
Ben Stiller sprinkles a lot of "Star Trek" references into his movies.
Not only is Stiller's production company, "Red Hour Films," a reference to an episode from the original series, but he has also thrown "Star Trek" references into his films ranging from "Tropic Thunder" to "Zoolander."
He also revealed at the 82nd Academy Awards he owns two pairs of Spock's ears signed by Leonard Nimoy.
Olivia Wilde says she's a Trekkie.
Wilde told i09 she's been a fan since young.
"I grew up as a Trekkie, which is really funny,"said Wilde. "I think 'Star Trek,' they were always great female roles, but there's no reason the captain shouldn't be a woman."
