"Star Trek" celebrated its 50th anniversary yesterday and, to celebrate the anniversary, "The Late Show with Stephen Colbert" welcomed George Takei as a guest. Takei played Sulu on the original "Star Trek" series, which debuted in 1966, and in six feature films. He's since become a beloved pop culture figure and advocate for LGBT rights.
During his appearance on "Late Show," Takei explained how "Star Trek" filmed sequences of the Enterprise coming under attack -- a process that involved camera tricks and not hydraulics. Instead of the ship jostling, the episode's director would just yell "left" or "right" and everyone on the bridge would quickly shift in that direction.
Colbert of course couldn't resist putting the Ed Sullivan Theater on red alert and going through the attack motions with Sulu. "I can't wait to go back in time and tell myself I got to do that with you," said Colbert once the commotion stopped. You can watch the interview segment below, with the "red alert" going off around the 5:30 mark.
