Leonard Nimoy has spoken about his possible return in the final season of Fringe.
Speaking to SciFi Now, Nimoy reiterated the possibility of reprising his role as the enigmatic William Bell in the fifth and final season of the FOX series:
“It will depend on what they have in mind for the character. There are a lot of issues that have to be dealt with, but we’ll be talking.”
Nimoy hinted that Bell — who winds up trapped in amber in the 2036 arc — could become more deranged:
“The William Bell character started as a very intelligent and rational character. I think he’s still very, very intelligent, but I’m not quite so sure that he’s rational anymore.”
Fringe returns this fall on FOX for one final chapter.
