In case you didn't know, I'm actually a big Trek fan. This is an unusual time in the Trek world: no active series, no movies in production. However, you can't keep Trek down.
First, there is the new Star Trek: The Original Series - Remastered, which adds modern day digital effects and cleanups to the series that started it all (Kirk, Spock, McCoy). Essentially, reruns of the series are being shown across the country (44/Digital 12, here in the Bay Area), with new sequences and digital enhancements. See for yourself:
Next, Tim Russ, who played Tuvok in Star Trek: Voyager, has created a new series of "webisodes," called Star Trek: Of Gods and Men, featuring original content and mini-movies. There are an...ahem...galaxy of famous Trek actors in the episodes, including Nichelle Nichols (Uhura), Grace Lee Whitney (Janice Rand), and Walter Koenig (Chekhov) from The Original Series; Alan Ruck from Star Trek: Generations (yes, and Ferris Bueller), as well as several actors from Star Trek: Deep Space Nine and Star Trek: Voyager.
Finally, J.J. Abrams of Lost fame has taken over the Star Trek movie franchise. He's brought in a lot of his collaborators from Lost and Alias; he's keeping fairly closed-mouth about the plot, but the teaser poster seems to suggest it's going back to the days of Kirk and Spock. No casting news yet, but The Trek Movie Report is on top of EVERY detail.
Looks like Trek will continue to live long...and prosper.
