I’ve used the phrase “cautiously optimistic” in regards to the new Star Trek movie so many times I’ve lost count – but it’s looking like I was right all along. I’ve probably been a Trekkie longer than a lot of you who are reading this have been alive, and my favorite series of all is The Original Series – and I don’t have a problem with J.J. Abrams’ rebirth of Star Trek based on what I’ve seen and read so far.

And as far as I’m concerned this new Star Trek trailer seals the deal.

If you didn’t make it out to see Watchmen, here’s the brand new trailer that’s attached to it. If you thought the previous trailers made this look good, or maybe they started nudging you towards acceptance but you’re still on the fence, this one should convince you this is probably going to be awesome AND faithful to the spirit of the original.

Check it out for yourselves:

Now tell me that didn’t rock your world. I will be perfectly honest and tell you that I actually got chills at the very end of this damned thing. This new trailer even smokes the previous one.

Of course a “killer app” of a trailer doesn’t guarantee a nirvana movie experience (see my Watchmen review for an example of that), but I’m keeping my fingers crossed that Abrams and company will deliver.

Oh, and thanks to Collider.com, we now know the running time for the film: 2 hours and 20 6 minutes. To me, that is also great news – plenty of time to deliver a decent story.

Star Trek opens on May 8, 2009.
