EXCLUSIVE: Another key Weeds player is set to return for the series’ upcoming eight and likely final season. I’ve learned that Justin Kirk has closed a deal for Season 8 of the dark Showtime comedy. He joins the series’ star Mary-Louise Parker, who was signed before Weeds was renewed for Season 8 in November, and Kevin Nealon, who recently finalized his deal to return for one last season. Both Kirk and Nealon have broadcast pilots — Kirk plays the lead of NBC’s single-camera comedy pilot Animal Kingdom, Nealon co-stars on another NBC comedy pilot, Isabel, with the new projects in first position to Weeds. It appears that everyone on the Jenji Kohan’s show is moving on (Kohan herself has a new series for Netflix), but not before one final hurrah with Season 8. Kirk, who was among the sought-after actors this pilot season with multiple offers, has recurred on ABC’s Modern Family. The actor, repped by UTA and Management 360, co-stars in the movie Goats, which premiered at Sundance.
