Rachel Weisz is being lined up to play Jackie Kennedy in new movie 'Jackie'.

The British actress would play the iconic US First Lady in the biopic, which tells the tale of the four-day period between President John F. Kennedy's assassination and burial in November 1963.

Rachel's fiancee Darren Aronofsky will direct and produce the film - which would be their second collaboration following on from critically acclaimed but commercially unsuccessful 2006 movie 'The Fountain'.

Noah Oppenheim has written The Script, according to Entertainment Weekly.

No other names are yet attached to the movie.

Rachel - who won a Best Supporting Actress Oscar for her performance in 'The Constant Gardener' in 2005 - has a number of movies coming out in the near future, including thriller 'Dream House' with Daniel Craig and Naomi Watts and western drama 'Unbound Captives' with Robert Pattinson and Hugh Jackman.

She is also rumoured for a role in the upcoming James Bond movie, due for release in 2011.
