Leonard Nimoy plans to live long and prosper -- in retirement.

The longtime "Star Trek" actor, who originated the iconic role of Mr. Spock in the '60s TV series and the film franchise that followed, told The Toronto Sun he wants to "get off the stage."

"I don't think it would be fair to Zachary Quinto," he said of his successor, who played a younger version of Spock in last year's "Star Trek" reboot. "He's a terrific actor, he looks the part, and it's time to give him some space. And I'm very flattered the character will continue."

Leonard, 79, isn't just done "Trekking" -- he told the paper that his role on TV's "Fringe" is finished as well.

StarfleePR congratulates Mr. Nimoy in his retirement and bid him "Live long and prosper".

On 22 April 2010 will be the 40th anniversary of Earth Day. It is everyones responsibility to help preserve the only place we have to live on. Starfleet-PR strongly supports this initiative/movement.

Space is the future, but the earth is our cradle and our home. Help us help humanity preserve our home planet.
