“Weeds” star Mary-Louise Parker has signed on to star alongside Michael Douglas in Brian Koppelman and David Levien’s “Solitary Man.”

Written by Koppelman, the follows a former owner (Douglas) of a car dealership chain whose career and marriage were destroyed by his business and romantic indiscretions.

According to Variety, Parker is playing a high-powered society sweetheart of Douglas' character.

Susan Sarandon, Danny DeVito and Jenna Fischer co-star in the project, which heads into production later this year.

Parker, whose credits include “Angels in America” and “The West Wing,” also recently starred in “The Spiderwick Chronicles.”

Final word: I adore “Weeds” and love Mary-Louise Parker. Enough said!
