As production is finally underway on the sequel to J.J. Abrams’ Star Trek, fans are speculating away as to what the sci-fi follow-up will entail. We know that pretty much every major cast member from the first film is returning, and Benedict Cumberbatch is onboard as the film’s villain (which may or may not be Khan). Plot details are firmly under wraps in Abrams’ super secret, high-security mystery box, but writer/producer Roberto Orci recently spoke a bit about how the sequel will differ from the 2009 film.  Hit the jump to see what he had to say.Interacting with fans over at Trek Movie, Orci answered a couple questions about the untitled sequel. First up, he confirmed that the budget for the film is more than the 2009 reboot. This was pretty much a given, as the motto for most sequels is “bigger and better.” The pricetag for the first flick was a reported $150 million, so Abrams and Co. must have something pretty impressive up their sleeve for the sequel in order to top that already high number.Continuing with the “bigger and better” sequel model, Orci answered affirmatively when asked if the scope of the film is bigger than Trek 2009. Again, this was a given, but it’ll be interesting to see where they take things. Star Trek was pretty damn epic in scope, incorporating ice planets, space battles, and time travel.  Orci, Alex Kurtzman, and Damon Lindelof worked for a really long time on the script, so hopefully they found an interesting and entertaining way to build upon what they started in the first film.Finally, when pressed to provide details on what kinds of “improvements” were made to the engine room on the Star Trek Enterprise, Orci responded, “You’ll see more of it.” Abrams famously shot the engine room scenes for Star Trek in a Budweiser brewery, so I’m interested to see whether they’ll build new portions on a soundstage or if they’re using more of the beer factory.These little tidbits of information aren’t much, but on such a highly anticipated project as this one, we’ll take what we can get. Personally, I’m hoping that plot details remain scarce for as long as possible. The pic doesn’t open for over a year, and there’s no fun in spoiling a good surprise this far out. The untitled Star Trek sequel hits theaters in post-converted 3D on May 17th, 2013.
