Sundance Selects has acquired North American rights to Andrew Haigh’s 45 Years, the drama starring Charlotte Rampling and Tom Courtenay that had its world premiere this week in competition at the Berlin Film Festival. The specialty label also released Haigh’s last film, 2011’s Weekend.

The pic, based on the short story by David Constantine and adapted by Haigh, centers on Kate (Rampling), who is in the middle of preparations for her 45th wedding anniversary when her husband Geoff (Courtenay) receives the news that the body of his old girlfriend, who died 50 years earlier in a fatal accident in the Swiss Alps, has finally been found, frozen in ice and time. Geoff retreats into a distant world of memories while Kate endeavors to suppress her burgeoning jealousy and anxiety with pragmatism.

Tristan Goligher of London-based The Bureau produced, and Christopher Collins, Lizzie Francke, Sam Lavender, Tessa Ross, Richard Holmes and Vincent Gadelle executive produced. It was financed by the BFI, Film4 and Creative England and co-developed by Film4 and the BFI.

The deal was negotiated by Sundance Selects/IFC Films’ Arianna Bocco with Match Factory on behalf of the filmmakers.
