While a world of Trekkers believed the new J.J. Abrams Star Trek would premiere Tuesday in Australia, Leonard Nimoy made a surprise appearance Monday night in Texas to screen the film for an unsuspecting audience.

A theater full of Trek fans showed up in Austin, Texas, thinking they were going to see a new print of the classic Star Trek II: The Wrath of Khan and 10 minutes of Abrams' reboot, all organized by Ain't It Cool News.

But the original Spock shocked the house by announcing they would in fact see the entire new movie just hours before it made its international bow in Sydney.

The early fan reviews on Twitter are running almost entirely positive so far.
