EXCLUSIVE: Earlier this week we brought you news that Allison Janney and Andrew Rannell drama Miss You, Love You had been picked up by HBO for the U.S. Today, we can update that the film is headed to the Cannes market with Architect, which is handling international sales.

The Jim Rash-written and directed project had a secret screening at Sundance, which was attended by Julia Roberts, and HBO has made it an Original to debut on May 29th stateside. Architect will be screening it on the Riviera next month.

The film follows a blunt, grieving widow, Diane Patterson (Janney), who is forced to plan her husband’s funeral with a total stranger: her estranged son’s assistant, Jamie Simms (Rannells). As they fumble through grief and their strange, darkly funny circumstances, buried secrets and long-held resentments surface, but their partnership becomes an unlikely conduit for connection, laughter, and healing for this mother and her unexpected surrogate son.

Bonnie Hunt, Suzy Nakamura, Oscar Nuñez and Lisa Schurga also star.

The film is produced by Kevin Walsh, Nat Faxon, Gigi Pritzker and Rachel Shane for Madison Wells. Michael Bowes serves as exec producer, Tammy Allen is co-producer and Liz Lippman is an associate producer.

Architect Calum Gray said: “Jim Rash is a sensational filmmaker who has been making us laugh, reflect and cry for over a decade now. Miss You, Love You is an absolute tour de force of his creative prowess and in Allison Janney and Andrew Ranells he has found two truly magical actors who transmute this beautifully constructed script into utterly compelling viewing. Miss You, Love You is fundamentally a film about human connection; the maddening delight of it, the difficulty in establishing it, the release when it finally, meaningfully happens – modern audiences will find such richness, beauty and laughter in this movie.”
