The original Captain James T Kirk has quashed rumors that he could make a cameo in the upcoming sequel.
"I don't think that JJ Abrams knows what to do with me," the actor told Geek Speak. "Age and change in body shape."
Shatner had previously been billed to appear in Abrams's 2009 Star Trek movie, but was not included because the director was unable to fit in a sufficiently large role for his character.
Shatner's acting colleague Leonard Nimoy reprised the role of Spock in the previous film, but has said that he will not appear in the sequel.
Star Trek into Darkness stars Chris Pine, Zoe Saldana, Zachary Quinto, Benedict Cumberbatch, Simon Pegg and Alice Eve.
The movie will open in UK and US cinemas on May 17, 2013. Watch the trailer below:
