Brent Jay Spiner (born February 2, 1949, Houston, Texas) is an actor best known for his portrayal of the android Lieutenant Commander Data in the television series Star Trek: The Next Generation and four subsequent films. He also guest starred on the subsequent series Star Trek: Enterprise. He is also known for his role of Dr. Brackish Okun in Independence Day. He has also enjoyed a career in the theater and as a musician. In five episodes of Night Court, he performed in a memorable role as farmer Bob Wheeler with Annie O'Donnell (Amy's mother (Mrs. Fowler)).
In "The Russian Rocket Reaction," Brent Spiner attended a party hosted by fellow Star Trek actor Wil Wheaton. At the party, he became a mortal enemy of Sheldon after breaking the seal and opening a signed, mint-condition, limited-edition Wesley Crusher action figure. Though he offered autographed Data dolls as compensation, Sheldon did not forgive him. However, Leonard and Raj attempted to take advantage of Brent's offer and, after some negotiating by Brent Spiner, both will receive the collectibles for $30 with the condition that Mr. Data will attend Leonard's birthday party. Sheldon portrays Mr. Data in "The Bakersfield Expedition" even though he is one of his mortal enemies.
