Colin Firth and Scarlett Johansson are being pursued for roles in Danny Boyle's 'Trance'.
The Oscar-winning actor is set to replace Michael Fassbender in the art heist thriller, opposite Scarlett as a character named Elizabeth.
It was previously thought James McAvoy - who stars alongside Michael in 'X-Men: First Class' - would be taking over the role, despite already being cast in another character in the film, but Twitch Film now reports 'Slumdog Millionaire' director Danny is keen to get British star Colin on board.
However, Scarlett is in competition with 'Star Trek' actress Zoe Saldana and Melanie Thierry for the part.
If she was to get the role, it would be the second film they had starred in together following their work on 'Girl with a Pearl Earring'.
Little is known about the script for 'Trance', but it is expected for release in 2013.
Since winning the Academy Award for Best Actor in 'The King's Speech' earlier this year, Colin has recorded a leading part in 'Gambit' opposite Cameron Diaz and will next be seen in Cold War drama 'Tinker, Tailor, Soldier, Spy' with Gary Oldman, Tom Hardy and Benedict Cumberbatch.
