Jessica Chastain will star in the comedy-drama “Losing Clementine” from award-winning Argentine filmmaker Lucia Puenzo.

“Better Call Saul” scribe Ann Cherkis is penning the script.

“Losing Clementine” is adapted from Ashley Ream’s acclaimed novel of the same name. Sentient’s Renee Tab acquired the book last year, during which time she developed the script, packaged the project and raised the financing. Tab will produce with her partner Christopher Tuffin alongside Freckle Films’ Chastain and Kelly Carmichael. Miller Way’s Michael and Jeeny Miller will executive produce alongside Sentient’s Jake Martin and Maryam Lieberman, and Cherkis.

The story follows world-renowned artist Clementine Pritchard (Chastain) who, after flushing away her meds, gives herself 31 days to tie up loose ends before killing herself. While checking off her bucket list, she uncovers secrets about her family and the tragedy that befell her mother and sister.
