Ritter will reprise her role as Gia Goodman in the film, which was funded by fans via a Kickstarter.com crowdsourcing campaign, and Hansen will be back as wealthy DICk Casablancas.
Announcing the news in a statement on Friday (14Jun13), Ritter wrote, "I'm thrilled to be reprising my role of Gia Goodman in the Veronica Mars movie. It's gonna be very juicy Marshmallows!!!!! Aaahhhh!!!! Forgive my over-use of exclamation points. Since you can't hear me squealing, I'm reduced to excessive punctuation. Ha!"
Hansen filmed a bizarre comedy dance video featuring Veronica Mars herself, Kristen Bell, to announce his involvement, saying, "I can't express how excited I am to be a part of this."
Other returning cast members include Kristen Bell, who played the title character on Tv, Jason Dohring, Chris Lowell, Francis Capra, Tina Majorino, Amanda Noret, Sam Huntington and Daran Norris.
Production on the film is scheduled to begin on Monday (17Jun13).
