Patrick Stewart says there is romance and sex in the new Star Trek film.
But he says his character Captain Picard isn't involved in any of it.
He's also revealed Star Trek: Nemesis will have a new kind of alien.
"Romulus has a sister planet called Remus," Stewart tells www.tvguide.com. "So you're going to meet the inhabitants of that planet, the Remans, who are quite unlike anything you've seen before.
"I think they might be the most successful aliens our makeup designer Michael Westmore has ever produced, I even include the Borg in saying this," Stewart says.
"He's brought an alien race to life in an entirely convincing way. There's something very novel and unique in their design. They're imposing and sinister in a very different way from the Borg."
Star Trek: Nemesis will be released in Ireland in December.
