Producer Nina Jacobson revealed that the duo are currently negotiating contracts for the project, which will be directed by An Education's Lone Scherfig.
"That is supposed to go this summer in London with Lone Scherfig directing and Anne Hathaway and Jim Sturgess," Jacobsen said.
One Day centres on Dexter and Emma, who meet during their graduation in 1988 and decide to reunite for one day every year for the next 20 years. The movie is based on David Nicholls's 2009 novel.
