Actor Jason Dohring has officially signed on to reunite with Kristen Bell for a movie adaptation of cult Tv show Veronica Mars after an online fan fundraiser drew more than $4.5 million (£2.8 million) in donations.

Series creator Rob Thomas set up the campaign on 13 March (13) in a bid to raise enough cash within 30 days to finance the project, and the $2 million (£1.25 million) target was hit less than 24 hours after its launch; by Thursday (04Apr13), devotees had more than doubled the original goal, with eight days still to go.

Now Thomas has given fans more reason to celebrate - Dohring, who played bad boy Logan Echolls on the show, is onboard to join Bell in the movie.

In an email to the donors, he writes, "We now have three actors officially cast. Veronica. Logan and the waiter who says, 'Your check, sir.' Don't worry. We're busily working on bringing your favorites into the fold. As a Veronica Mars backer, you'll be the first to know."

Bell, who will reprise her role as the titular character, has been instrumental in rallying support for the fundraiser via, and is aiming to set a new Kickstarter record to have the project with the most backers in the history of the website.

The current record is 87,000, and the Veronica Mars effort already boasts more than 68,000.
