When one is murdered, the remaining members set out to solve the mystery.
Gugino will play Sally Jupiter, a burlesque dancer-turned-costumed heroine and sex symbol the Silk Spectre who is part of the Minutemen, a group of heroes who preceded the Watchmen. She also is the mother of the new Silk Spectre (Akerman). Gugino is expected to portray Jupiter in varying eras, playing different ages throughout the movie.
Zack Snyder (300) will direct the film, which is set to start shooting in the fall in Vancouver.
