Hope I don't get into trouble for posting a new thread here...
I read an interview with Pine in todays Mirror
(British newspaper). In it they ask - "William Shatner made seven Star Trek feature movies. How many do you think you will make?"
He is quoted as replying "I'm commited to two more at this point. Er, not sure if I should have said that [laughs]"
Unfortunately I cannot find a weblink to this interview.
