The pair - who starred together in the 'Pirates of the Caribbean' trilogy alongside Johnny Depp - are to appear in 'The Fever Returns', a new film based on cult disco movie 'Saturday Night Fever'.
The original film, which was released in 1977 and starred John Travolta, was set in Brooklyn but movie bosses are reportedly planning to base 'The Fever Returns' in Hoddesdon, Hertfordshire, England.
It is not yet clear if the movie will be a sequel or remake of 'Saturday Night Fever'.
Earlier this week, Keira admitted she is unsure of the type of movie roles she wants to take on next.
She said: "I haven't quite found what I'm looking for yet. What I'm not capable of doing is saying, 'For my career, I should be doing this right now.' I can't do that because I can't try and be interested in something that I'm not."
"It has to be about something that I do actually want to talk about. It can be really embarrassing and depressing and very cynical if you sit there and go, 'Well, I got a really big pay cheque.' "
