The "Veronica Mars" movie cast is growing: Enrico Colantoni has officially signed on to reprise the role of Keith Mars, Veronica's father.

So far the cast of the "Veronica Mars" movie includes Kristen Bell, Jason Dohring and Colantoni. Additional casting is expected with production set to begin in Los Angeles in June.

Series creator Rob Thomas and Colantoni released this video following the casting announcement.

In an email to "Veronica Mars" movie backers, Thomas praised Colantoni. "I didn't write Keith Mars with Rico in mind, but when his name came up on a casting list, I said, 'That's the guy,'" he wrote. "We didn't take anyone else to network. There was no plan B."

Colantoni also released a video to fans following his casting announcement.

  • Aaron Paul

    Before he was taking home Emmys for "Breaking Bad," Aaron Paul guest starred in the Season 1 episode "Silence of the Lamb" as a suspect in the E-string Strangler case. His down and out rocker could easily pop up when Veronica Mars returns to Neptune, especially since Paul will be done filming "Breaking Bad" soon.

  • Lucy Lawless

    The "Xena: Warrior Princess" star appeared in the Season 2 episode "Donut Run" as an FBI agent investigating the disappearance of Duncan Kane, who kidnapped the daughter he had with Meg. Lawless' FBI agent could come back to town to tackle the murder that brings Veronica Mars back.

  • Max Greenfield

    Max Greenfield played the lovable Deputy Leo on 11 episodes of "Veronica Mars." A one-time love interest for the titular character, Leo could easily be in the film ... and will likely make an appearance! "Max is driving a hard bargain to reprise his role as Deputy Leo. His direct quote was that he'd take no pay and fly himself to set," <a href="http://www.eonline.com/news/398514/veronica-mars-movie-scoop-rob-thomas-dishes-on-possibly-bringing-series-back-to-tv-max-greenfield-s-return" target="_blank">series creator Rob Thomas told E! Online</a>. "He'll be the Leo we've known and loved. We'll find him working as a detective for the San Diego Police Department."

  • Alyson Hannigan/Charisma Carpenter

    "Buffy the Vampire Slayer" veterans Alyson Hannigan and Charisma Carpenter both appeared on "Veronica Mars": Hannigan played Logan's sister, Trina, and Carpenter played Logan's former lover who was in with the Fitzpatrick gang family. Carpenter's character was left for dead ... but there's always the magic of TV.

  • Jonathan Taylor Thomas

    "Veronica Mars" was one of Jonathan Taylor Thomas' few TV appearances since the end of "Home Improvement." He played an FBI agent undercover at the high school to thwart a bombing. His character could partner up with Lawless' and return to Neptune ...

  • Jessica Chastain

    Oscar-nominee Jessica Chastain appeared in one episode of "Veronica Mars" in Season 1 as Veronica's pregnant neighbor Sarah. It's a stretch, but if Chastain wants in, Thomas could easily write a cameo.

  • Armie Hammer

    Armie Hammer guest starred in the Season 3 episode of "Veronica Mars" titled "Wichita Linebacker" as Kurt, a football player who hired Veronica to find his missing playbook.

  • Amanda Seyfried

    Amanda Seyfried auditioned for the role of Veronica Mars, but wound up playing her dead best friend Lilly Kane. The character's murder was at the center of Season 1. The show was big on flashbacks, making Seyfried's appearance more likely than Chastain's.

  • Joss Whedon

    "Buffy the Vampire Slayer" creator Joss Whedon guest starred as an employee of a rental car agency. Veronica Mars might need some wheels when she returns to Neptune ... "It was unfettered joy," <a href="http://www.buzzfeed.com/adambvary/joss-whedon-on-kickstarter-and-firefly" target="_blank">Whedon told Buzzfeed of his reaction to the "Veronica Mars" movie</a>. "A) I thought it was an awesome and ballsy move. B) I love V. Mars and want more of it. And C) It feels like a real game-changer. Like, not since Louis C.K. [selling his comedy special directly online]."

  • Adam Scott/Leighton Meester

    Adam Scott played a teacher who is accused and later confirmed to have slept with and impregnanted students. In the Season 1 episode "Mars vs. Mars," Leighton Meester played his accuser. She later popped up as Carrie Bishop. Since the plot of the "Veronica Mars" movie involves the 10-year Neptune High reunion, Meester's appearance would be very easy to write in.

  • Krysten Ritter

    Before she was the "B---- in Apt. 23," Krysten Ritter played Gia Goodman, daughter to mayor/molester Woody Goodman and one of Veronica's Neptune High classmates. <a href="https://twitter.com/Krystenritter/status/313735974330986496" target="_blank">Ritter tweeted that she wants in </a>so maybe we'll see her at the reunion.

  • Michael Cera/Alia Shawkat

    "Arrested Development" stars Michael Cera and Alia Shawkat both appeared in the Season 2 episode "Rapes of Graff" that served as the main case of the first part of "Veronica Mars" Season 3. Cera played an awkward tour guide and Shawkat a rape victim.

  • Dianna Agron

    "Glee" star Dianna Agron played one of Veronica's college classmates. Maybe her character could've stuck around Neptune once she graduated college?

  • Aaron Ashmore

    Aaron Ashmore (left) played Troy Vandergraf, one of Veronica's love interests who later tried to use her to smuggle drugs and run off with his girlfriend. She of course foiled his plans. With his twin brother on "The Following," we think the "Smallville" alum could revisit his TV roots too.

  • Jane Lynch

    Jane Lynch appeared as a teacher at Neptune High before she starred in "Glee" and "Party Down." Hey, sometimes teachers attend the reunions ...

  • Ken Marino

    Ken Marino appeared in several episodes as scrupulous private eye Vinnie Van Lowe. In Season 3, his character ran against Keith Mars (Enrico Colantoni) for sheriff of Neptune. Keith lost the election and it's easy to believe Vinnie is still head of sheriff's department 10 years later.

  • Paris Hilton

    Paris Hilton appeared in an early Season 1 episode as one of Veronica's high school classmates and Logan's girlfriend. Again, a 10-year reunion makes her appearance an easy one, especially since Hilton doesn't seem to be doing that much lately.

  • Valorie Curry

    "The Following" star Valorie Curry played Jane, one of Wallace's girlfriends in Season 2 of "Veronica Mars." The 10-year reunion plot makes her appearance very doable.
