Four-time Emmy winner Allison Janney (’The West Wing’) will appear in multiple episodes as a U.S Marshal who butts heads with Mary, while Steven Weber (’Studio 60,’ ABC’s upcoming ‘Happy Town’) will play a charming FBI agent.
Also, Tess Harper (’No Country for Old Men’) will guest as a take-no-prisoners federal prosecutor, Josh Cooke (’Four Kings’) will play the very first witness Mary and Marshall handled, and Oscar/Emmy/Grammy winner Rita Moreno is heading for some wedding planning, as Raph’s (Cristian de la Fuente) Aunt Rita.
