It seems the idea of a Chuck movie is still somewhat alive, thanks to the Kickstarter campaign that raised the necessary funds for a Veronica Mars movie in less than 24 hours.
Zachary Levi wants 'Chuck' movie following 'Veronica Mars' Kickstarter
Hopefully Zachary Levi can get this done. I have quite a bit of faith that the Chuck fans could raise $2M (or whatever it would take to make a Chuck movie) if they followed a similar path. This really needs to get done so that they can leave the story at a place other than where they left it in the series finale.
