Rachel Weisz has reunited with “The Constant Gardner” helmer Fernando Meirelles for his latest project, “360.”

Peter Morgan is penning the script for the pic that follows pairs of characters and their sexual encounters. Project is based on the 1900 play “Reigen” that inspired French drama “La Ronde” and has provided the dramatic structure for scores of plays and films.

The pic will be cofinanced by Austrian broadcaster ORF and BBC Films.

Andrew Eaton will produce, with David Linde exec producing. No start date has been set.

Weisz and Meirelles first worked together on 2005’s “Constant Gardener,” for which Weisz earned a supporting actress Oscar. Focus Features distribbed that pic at a time when

Linde was co-prexy of the company.

Meirelles most recently directed “Blindness” with Julianne Moore and Mark Ruffalo.

Weisz, whose lastet feature “The Whistleblower” bowed at Toronto, will be seen next in “Dream House” with Daniel Craig.

Weisz continues to be repped by CAA. Meirelles is repped by WME
