American film actor, born in 1969 and a lifelong Star Trek fan, who made a cameo as the Excelsior officer who wakes Captain Sulu in Star Trek VI: The Undiscovered Country.
Christian Slater is an American actor known for Heathers, Pump Up the Volume, True Romance and, later, the television series Mr. Robot.
Already a star in 1991, he asked for a small part in Star Trek VI: The Undiscovered Country, on which his mother, Mary Jo Slater, was casting director. He appears as a communications officer on the night watch of the USS Excelsior who rouses Captain Sulu in his quarters with word from Starfleet about the search for the Enterprise.
Sulu instructs him to reply that the Excelsior has no idea where the Enterprise is. The scene lasts only moments and is one of the best-known celebrity cameos in the film series.
