Rachel Weisz boards Meirelles' '360'

Rachel Weisz is joining Fernando Meirelles' upcoming film "360," which reunites the actress with the director after "The Constant Gardner." Peter Morgan ("The Queen," "Frost/Nixon") is writing the screenplay.

Variety says the film follows a pair of characters and their sexual relations, but that's pretty much all that has been revealed about the plot so far. It's based on the 1900 play "Reigen" and the drama "La Ronde."

Meirelles also directed "City of God" and "Blindness." As for Weisz, she starred in "The Lovely Bones" recently. She's got "The Whistleblower" and "Dream House" coming to theaters in the near future.
