Johnson Back in Action: Don Johnson’s new action drama, “Nash Bridges,” premieres March 29 on CBS in the Friday 10 to 11 p.m. hour vacated earlier this month by “Picket Fences.” Johnson stars as a member of San Francisco’s elite Special Investigators Bureau who earns raves for his police work, but has trouble juggling his personal responsibilities--including a pair of ex-wives and a 16-year-old daughter. Johnson’s co-stars on the series include Annette O’Toole, Jamie Gomez and Cheech Marin, who plays a recurring role as Johnson’s wisecracking ex-partner.
