He was an understudy in "Joe Turner's Come and Gone," his favorite play, by his favorite playwright, August Wilson, and in his favorite role, Herald Loomis. The star lost his voice, and Nyambi went on.
That night, June 12, 2009, he went on.
LaTanya Richardson Jackson, who starred in the play, "gave me a kiss on the cheek and said, 'You are never going to be the same,' " he recalls.
His second pivotal actor's moment had him in "The Merchant of Venice" starring Al Pacino.
"It was so amazing being there with Al," Nyambi says. "He was just one of the guys."
He also acted with Mandy Patinkin, just after graduate school at NYU. Nyambi attended Bucknell on a basketball scholarship, starting as a computer science major.
"I found myself at 4 a.m. still trying to figure out how to make a clock move 12 seconds," he says. "And practice was at 6, so I dropped out and became an art major because I draw. ... (Painters) are not famous until they die, and I don't want to wait until then."
Clearly, Nyambi, an eventual Business major, didn't have to.
Hometowns: Born to Nigerian parents in Oklahoma; reared in Houston, Dallas and Virginia; now lives in New York and Los Angeles.
Cool resolution: Watched 365 movies last year after becoming irritated with himself for holding onto a Netflix DVD for a year.
