Actor William Shatner says he would be "open" to a return to Star Trek, but he believes it will never happen.
The 85-year-old played Captain James Kirk in the classic 1960s television series and the first seven Star Trek films.
He has been linked with a return to the Starship Enterprise since director JJ Abrams rebooted the movie franchise in 2009.
Speaking at the Saturn Awards in Los Angeles, William said: "We'd all be open to it, but it's not going to happen.
"The fans would love to see it. Have them write to JJ Abrams at Paramount Studios."
William confirmed he will not appear in the upcoming film Star Trek Beyond, which stars Chris Pine in the role of Captain Kirk.
Reports suggested William could return to the sci-fi series after the late actor Leonard Nimoy reprised his role as Spock in the 2009 film Star Trek and its 2013 sequel Star Trek: Into Darkness.
Shatner praised JJ, who also directed Star Wars Episode VII: The Force Awakens, for making "wonderful" Star Trek films.
He said: "I think JJ Abrams solved the problem of the glass ceiling of the box office that we always hit and in making it a great ride.
"He's wonderful director and he's running with that franchise. I think it's great."
William will appear at Boston Comic Con in August to mark the 50th anniversary of the classic Star Trek television series.
