There are not supposed to be emotions or a huge desire to look attractive on Vulcan. Plus, there seems to be some affinity for Moe Howard.

Leonard Nimoy spent decades sporting the famous Spock hairstyle, and it's because of that legacy that "Star Trek 2" star Zachary Quinto says he now has to live with.

"My eyebrows are shaved and I do my hair in a way that people don't know I actually have my horrible Spock hair," Quinto recently to E! Online at the Producers Guild Awards. Production has just started, and despite his hair, everything seem to be running smoothly under director J.J. Abrams.

"It's been really great," Quinto said. "We've been shooting for a week and a half, and it's been an incredible return to that world."

Unlike the first "Star Trek" film in 2009, the cast has received a script that is still "in progress." Yes, the words of Roberto Orci, Alex Kurtzman and Damon Lindelof have been finalized, but that doesn't mean tweaks aren't happening here and there. And because there's no writers strike this time out, such changes can actually take place instead of shooting a locked script.

"It was the middle of December, and finally I had to be like, 'We need to read the script,'" Quinto said. "They waited a pretty long time, but that's because they were working on it."

And they're still working on it. "Now it's really changing ... on a regular basis."

Quinto wouldn't provide many other details except to say that "Sherlock" star Benedict Cumberbatch is already on set, and is meshing well with the cast. Cumberbatch is rumored to be the lead villain in the film, and joins a British invasion that also includes Alice Eve and "Doctor Who" alum Noel Clarke.

"All of them have folded in so beautifully, and brought a whole new level of intelligence and sensitivity," Quinto said.

The movie got a little boost this past week on the hit CBS show "Big Bang Theory," where one of the lead characters (played by Emmy winner Jim Parsons) gets upset when his Spock cutout arrives as Quinto and not Nimoy. That episode was the fourth most-watched show of the week, behind three outings of Fox's "American Idol."

Production on "Star Trek 2" is expected to continue through the spring on the film, with a release set for May 2013.
