Amidst the series finale coverage, Zachary Levi, Yvonne Strahovski, and executive producer Chris Fedak were all asked about the possibility. Here's what they had to say:
USA Today: As for whether this is truly the end for a show that wouldn't die, Levi says he could see a continuation via an online film. Again, it goes back to depending on the fans.
"I genuinely believe that our fan base, if given the opportunity to spend $5 on an hour-and-a-half Chuck movie to buy online and keep, I think they would," he says. "That would be a really fun thing to do."
