Though primarily recognized for her many collaborations with husband David Mamet, actress Rebecca Pidgeon branched out on her own on occasion to tackle roles in a variety of film and television projects. But it was her being cast in Mamet's London production of "Speed-the-Plow" (1989) that sparked both a romance that turned into a long-running marriage, and prominent roles in the playwright's more invigorating work. After roles in "Homicide" (1991) and Mamet's adaptation of "Uncle Vanya" (PBS, 1994), Pidgeon had a pivotal role in the crime drama "The Spanish Prisoner" (1997) before delivering an astute performance in the period remake of "The Winslow Boy" (1999). Following more supporting parts in her husband's directorial efforts, "State and Main" (2000) and "Heist" (2001), she had a recurring role on "The Unit" (CBS, 2006-09) before going off on her own in "How to Be" (2008) and "Red" (2010). But it was her work with Mamet that provided Pidgeon with her most demanding roles, allowing her to display considerable skills that might have otherwise remained under wraps.
