Well... it's nice to know for certain that the build-up to Star Trek Into Darkness will be constant pranking from J.J. Abrams and co.
The director was recently on Conan and touted that he had snuck out a short clip from the highly-anticipated Star Trek sequel to the show the audience. He wasn't lying! Unfortunately, it was only three frames of the movie, the sum total of which you can see above.
But hey! Spock wandering around a volcano is better than nothing. You can see the entire video over on The Mary Sue.
