The hardworking Martin Donovan joined Gould on "Weeds" this season as a [sorta] recurring character-- a single father who flirts with mom/dealer Nancy (Mary Louise Parker). And his role is prominent in tonite's season finale.
"Weeds" airs on Showtime on Mondays, Wednesdays, and Fridays at 10 p.m. ET/PT. Check your local listings, etc. Check it out!-- it's very addictive.
Donovan was Roger in the WB pilot. Gould played David.
