Zoe Saldana has hinted the Romulans may play a part in 'Star Trek 2'.

The 32-year-old actress - who played linguistics officer Uhura in the J.J. Abrams-directed take on the 'Star Trek' franchise in 2009 - hopes the sequel will have storylines involving intimacy with Spock (Zachary Quinto) and mentioned the possibility of a physical altercation with the famed enemies of the Federation.

She told Empire Online: "I can maybe tell you what I'd like to see happen. For Spock and Uhura to really hook up. Or to get to do whatever physical activities. Kick some butt, some Romulan butt."

Karl Urban, who stars as nervous doctor Leonard 'Bones' McCoy in the movie, recently claimed he was looking forward to working on the follow-up because they had such a "great" time on the first film.

He said: "I'm hearing we will start shooting in September or November this year. I certainly hope J.J. will be back.

"He's a phenomenal director and we had such a great time working with him on the first one so fingers crossed."

'Star Trek' made $385 million at the box office worldwide upon its release.
