MILF-iliicious TV drug dealer Mary Louise-Parker has joined the cast of the Brian Koppelman and David Levien directed dramedy SOLITARY, where she’ll play the girlfriend of Michael Douglas’ car magnate character. In the film, Douglas’ character’s professional and personal life spirals out of control basically because he’s an unethical asshole. Needless to say, hilarity punctuated by self-actualization and emotional catharsis ensue. Susan Sarandon, Danny DeVito and Jenna Fischer round out the cast. Production is expected to begin next month from a script by Koppelman. Parker was most recently banging Mexican drug dealers/mayors on the hit Showtime series “Weeds” and can next be seen in the drama HOWL.
