Zoe Saldana hopes 'Star Trek 2' will contain romance.

The US actress - who plays linguist Uhura in the movie - admits she is holding out for more romantic scenes with Zachary Quinto (Spock) in the second film.

She said: "There was a huge acceptance and excitement with what director Jj Abrams and the writers - Alex Kurtzman and Roberto Orci - did with that twist.

"What they did was a huge gamble - and when it worked, it worked really, really well.

"It would be interesting to see what they are going to do with it. I really hope they keep the relationship and continue to explore it."

'Star Trek' changed the timeline of the original TV series, leading to an alternate universe where Spock's home planet Vulcan has been destroyed, an issue which confuses Zoe.

She told MTV.com: "At the same time too - this is coming from my mother, who is a Trekkie - I could be wrong, but I thought that Vulcans only mate every seven years.

"So now that the planet Vulcan has been extinguished, it's kind of interesting. Can Spock mate with a non-Vulcan? It's ok to consider such issues. I love it."

'Star Trek 2' is due for release in 2011.
