Zoe Saldana has confessed all of the Klingon she learned for Star Trek left her the minute the film wrapped.
The actress, who plays Uhura in Star Trek Into Darkness, learned the trekkie language for her role but admitted she can't remember any of it.
Zoe, 34, said: "I wish I knew it but I don't. I rehearsed it with the linguist and it was a wonderful experience.
"As soon as they said 'it's a wrap people' I completely forgot it so I hope when the fans see it they'll like my accent."
Zoe said she liked how much Uhura had moved on since the last film: "This time around it felt like [Uhura and Spock] had already warmed up to each other and there was a shorthand communication they had with each other."
Zachary Quinto, who plays her love interest Mr Spock in the film, said he could see why his character's girlfriend had problems with him.
He said: "It's a little more complicated this time around. There are some aspects of Spock's personality that Uhura has some issues with in this film and I don't blame her, but they work it out in the end."
He also said that his character might not find relationships easy but that he was willing to give them a go.
"I don't know how easy he finds it, but since Spock is half human I think he's compelled to try."
