Back in August, Leonard Nimoy claimed that he was retiring, but he has changed his mind about that with the news of a return to Fringe as William Bell.
His appearances on Fringe had been a favor to “the people who made the Star Trek movie,” according to Nimoy. When he was finished with his work on the show, Nimoy was asked if he would do more episodes in the future and he said “No, we’re done.” Instead, his plans included devoting time to his photography. “I am totally committed to the photography now,” he said.
TrekToday will provide more details on Nimoy’s Fringe appearance as information becomes available.
