Firefly

"Serenity"

Joss Whedon could not find an audience for his terrific TV series "Firefly," about a motley assemblage of free spirits aboard a jalopy of a spaceship with a mysterious passenger pursued by government operatives. Whedon earned a second chance on the big screen with an excellent continuation, but he still could not find an audience much beyond the show’s cult fan base. Nathan Fillion leads the cast as the ship’s captain whose teenage passenger (Summer Glau) is at the center of a dark interstellar mystery. Whedon offers an introduction and commentary, and the DVD has extensive deleted scenes and outtakes, plus a look at the show’s die-hard enthusiasts DVD, $29.98. (Universal).
