Leonard Nimoy has suggested that he could return to Fringe in the future.
The actor announced his retirement earlier this year and his Fringe character William Bell died in the recent season finale.
However, in a video on the official website, Nimoy said: "Do I think he's really dead? Do I think William Bell is really dead? This is science fiction. I have died in science fiction many times and somehow magically or scientifically come back."
He added: "Given that he has disintegrated, what happens in the future remains to be seen."
Fringe star John Noble has described the season two finale as "stunning".
