Doubt had the two trickiest supporting roles of the theater season, and in retrospect it's hard to imagine Pat Bowie's part going to anyone else. Bowie played Mrs. Muller, a black mother in the 1960s Bronx, whose young son may or may not have been molested by a parish priest. Bowie's sole scene came when she was summoned to the office of the school's headmistress, the very-stern Sister Aloysius. Aloysius voiced her suspicions, and Mrs. Muller, rather than being shocked or horrified, told the nun to mind her own business. Apparently, Mrs. Muller believed there were worse things than being diddled by a man of the cloth. Aloysius was horrified, and so was anybody who happened to be sitting in the audience. But in the 10 minutes that followed, Mrs. Muller became a genuinely sympathetic character — so convincing was Pat Bowie that you figured plenty of theatergoers must have come around to her side.
