More information is finally emerging about Larry David's mysterious movie project for HBO -- and it's all good news. According to The Hollywood Reporter, the film now has a title ("Clear History"), a synopsis, and a confirmed cast, which reads like a who's who of the Hollywood elite.

Joining Jon Hamm and Michael Keaton alongside writer-producer-star David are Bill Hader, Danny McBride, Kate Hudson, Eva Mendes, Phillip Baker Hall, Amy Ryan and JB Smoove. The project will be directed by Greg Mottola, and was co-written by "Curb Your Enthusiasm's" Alec Berg, David Mandel and Jeff Schaffer.

Here's the synopsis, per THR:

[The plot] centers on Nathan Flomm (David), a former marketing executive at a start-up electric car company who, after losing a fortune due to a petty argument with his boss, is publicly humiliated for walking away from his 10 percent of a company now worth billions. Ten years later, his marriage over and reputation ruined, Nathan has changed his identity and lives a simple life on a small island off the coast of Massachusetts under the new name of Rolly DaVore. But when his former boss (Hamm) shows up to renovate his summer mansion, Nathan vows to seek his revenge and drive his nemesis off the island.

  • Andrew Rannells, "The New Normal" (NBC)

    After a hilarious stint on HBO's "Girls" (which he'll also return to for Season 2), we're thrilled that Rannells ended his Tony-nominated run starring in "The Book of Mormon" on Broadway to play one-half of Ryan Murphy's new comedic leading gay couple on "The New Normal." His scene-stealing skills are still very much intact -- he goes head-to-head with co-stars NeNe Leakes and Ellen Barkin and still manages to get the last laugh.

  • Clare Bowen, "Nashville" (ABC)

    Yes, "Nashville's" big draw is the rivalry between Connie Britton's one-time queen of country music and Hayden Panettiere's up-and-coming starlet; but the real gem here is Bowen's Scarlett O'Connor, a sweet girl with an even sweeter singing voice. This Australian native might not be a big name in the States just yet, but it's only a matter of time.

  • Ed Weeks, "The Mindy Project" (Fox)

    British actor Weeks plays Jeremy Reed, the devilish doctor who tempts Mindy Kaling's title character to the dark side on "The Mindy Project." This is his first US TV role, and we're already expecting great things.

  • Danai Gurira, "The Walking Dead" (AMC)

    We only caught a glimpse of katana-wielding Michonne in the "Walking Dead" Season 2 finale, but it was enough to get fans excited for more. As our survivors seek shelter in the prison and meet The Governor (David Morrissey), they're gonna need someone who knows how to wrangle up zombies right, and Michonne's their girl.

  • Jacob Artist, "Glee" (Fox)

    Now that Puck (Mark Salling) has graduated from McKinley, there's a new generation of Puckerman in town -- Artist is signed on to play Jake, Noah Puckerman's half-brother, in Season 4. If he's even half as talented, sweet and prone to causing trouble, we'll happily have a slushie or two waiting in the wings with his name on it.

  • Laura Benanti, "Go On" (NBC)

    Benanti was a bright spot in NBC's drama flop "The Playboy Club" last season, but while the Broadway vet got to sing and shake her tail feather (literally), we didn't get to see her show off her comedy chops there or on her "Law & Order: SVU" stint. Now playing opposite Matthew Perry, there's great comedic potential and some sexual tension to mine.

  • Rob Evans, "America's Next Top Model" (The CW)

    Evans, a male model (and current <a href="http://www.huffingtonpost.co.uk/2012/06/08/tyra-banks-robert-evans_n_1580287.html" target="_hplink">Mr. Tyra Banks</a>), is stepping into some pretty big shoes <a href="http://www.huffingtonpost.com/2012/05/17/americas-next-top-model-n_n_1524091.html" target="_hplink">to judge "ANTM" this season</a>, and we have high hopes that he can pull it off. He's got the looks to keep us watching and the pedigree to critique this cycle's contestants ... we'll still miss Nigel Barker, Jay Manuel and J. Alexander, but this is a nice refresh.

  • Janet Montgomery, "Made In Jersey" (CBS)

    Montgomery made the final season reboot of Fox's "Human Target" bearable, popped up on "Entourage" and even danced around the company in "Black Swan," but this starring role is her true US TV breakout, and her convincing Jersey accent and go-get-'em attitude will make you forget she's actually a Brit.

  • Nat Faxon, "Ben and Kate" (Fox)

    There aren't many Oscar winners that could come to TV without fanfare ... but that's the case with Faxon, who brings all his funny sidekick experience up a notch to take on one of the lead roles (he's Ben) in this quirky family comedy. He's been around for a while, is a Groundlings member and, yes, even took home an Academy Award for Best Adapted Screenplay for George Clooney's "The Descendants" last year, which he co-wrote with director Alexander Payne and his writing partner Jim Rash, a.k.a. "Community's" Dean Pelton. TV is lucky to have him.

  • Tracy Spiridakos, "Revolution" (NBC)

    Spiridakos has done TV guest spots here and there (including a stint on Syfy's "Being Human" last season), but this is the show that should make her a star. "Revolution" has its issues, for sure, but even surrounded by more established stars, Spiridakos shines playing an emotional <em>and</em> gun-toting badass.

  • Camilla Luddington, "Grey's Anatomy" (ABC)

    <a href="http://www.huffingtonpost.com/2012/07/19/greys-anatomy-camilla-luddington_n_1687544.html" target="_hplink">Camilla Luddington is on call at Seattle Grace Mercy West hospital</a>. The "Californication" and "True Blood" alum will don scrubs on "Grey's Anatomy" this fall to play a (sexy) new doc, with the option to sign on as a series regular next season. Start placing bets now about who she'll hook up with first!

  • Stephen Amell, "Arrow" (The CW)

    Amell's most memorable TV role to date might be as Jason, the rival male prostitute on the last season of HBO's "Hung," but his new superpowers really suit him. As Oliver Queen, aka The Green Arrow, Amell has some big leather hoodies to slip into ... but we guarantee no one will complain about the way he fills them out.

  • Mercedes Masöhn, "666 Park Avenue" (ABC)

    Swedish-born Masöhn was a bright spot on Fox's ill-fated "Bones" spinoff "The Finder" -- and she's got quite the sense of humor -- but we're loving her in this darker role as one of the residents of a very haunted building. Cast alongside Terry O'Quinn, Vanessa Williams, Dave Annable and Rachael Taylor, she still manages to stand out as a Park Ave. resident to watch.
