The question “What TV show was cancelled too soon?” has plenty of good answers: Freaks and Geeks, Deadwood, Twin Peaks, Futurama (the latter two were revived, thankfully, and Deadwood is reportedly getting a movie). Though there are many good answers, there’s only one right answer: Firefly. Joss Whedon’s space Western got the ax from Fox just 11 episodes into its first run. Fan outcry (and strong DVD sales) moved Whedon to create Serenity, a feature-length continuation of the series that disappointingly has nothing to do with Seinfeld’s “serenity now.” Each year, Firefly fans, also known as Browncoats, stage Can’t Stop the Serenity, a screening of the film from which the proceeds go to charity. The 13th edition of the event in Pittsburgh is at the Parkway Theater and hosted by Jump Cut Theater.
