See a great film noir, then talk about it: “Touch of Evil,” starring Charlton Heston, Orson Welles, and Marlene Dietrich (in her favorite performance). Before the film starts, Film professor Terry Meehan will give a brief introduction and show a short video on how the movie opened in theaters in 1958, but was not actually “completed” until 1998. In effect, Orson Welles supervised his director’s cut from beyond the grave. The film starts at 6 p.m.
