Alma movie: Teaching Mrs. Tingle (1999)

The nasty old saw that "those who can't do, teach" certainly applies to Mrs. Tingle (Helen Mirren), whose abject jealousy of star pupil Leigh Ann Watson (Katie Holmes) drives her to harass and unfairly grade her -- and ends up placing Tingle at the center of a progressively more confused plot to clear Leigh Ann from false charges of stealing exam papers. At 19% on the Tomatometer, Teaching Mrs. Tingle received a failing grade, but Mirren was an inspired choice to play the icily imperious -- yet secretly quite vulnerable -- instructor.
