So, today's Sunday Mirror (a newspaper I would ordinarily go nowhere near) had a free special edition of Star Trek Magazine from Titan Magazines. A 16-page "taster" issue, including what I imagine are interviews from the real issue 145, the Movie Souvenir Special.
The bumper first issue is apparently out now (although I didn't spot it anywhere after looking around for Trek merchandise on Friday afternoon after the film), and is 68 pages (I presume future issues will be 32 pages or similar). The issue features the first two issues of the film prequel Countdown, as well as various other features, and film stickers. Obviously, it is intended for a younger audience, but I shall be picking it up as soon as I locate it!
I think this is a UK-only release, as there's nothing on Titan's US website about it.
More information can be found at Titan's official website here.
