Charlie Sheen may be erratic in his personal life, but he's still reliable at generating TV ratings gold. Sheen's new FX sitcom "Anger Management" debuted as the highest-rated premiere in FX history, attracting 5.5 million total viewers in its first half-hour episode and 5.7 million in its second, according to The Nielsen Company.

The number represents a big win for Sheen, who was fired from his last hit sitcom, "Two And Half Men," after a streak of unhinged behavior and clashes with his CBS corporate bosses.

The ratings also bode well for "Anger Management's" chances of sticking around for a long time. FX initially ordered 10 episodes of the sitcom, but the deal contains an automatic escalator clause that triggers a 100 episode order if it meets certain ratings benchmarks.

"Anger Management" received less than stellar reviews in the week leading up to its premiere. Critics called it a formulaic and lazy vehicle that Sheen was using to rehabilitate his image.

The show features Sheen playing yet another version of himself: Charlie Goodson, a former hot-headed minor league baseball player who's evolved into an anger management therapist with unconventional methods. The series is adapted from the 2003 film starring Jack Nicholson.

  • Zooey Deschanel (Jess), "New Girl"

    Totally "adorkable" in her flouncy dresses and bows, there's a fine line between Zooey Deschanel and her "New Girl" character Jess. Naive, happy-go-lucky and hopelessly flawed, Deschanel has said Jess is a teenage version of herself.

  • Lena Dunham (Hannah), "Girls"

    Drawn from her own experience as a 20-something Brooklynite, Lena Dunham created the angst-ridden, artistic Hannah Horvath. While Dunham bears striking similarities to Hannah, she's a little better off financially -- and hopefully having less awkward sex.

  • Alexis Bledel (Rory), "Gilmore Girls"

    She may have been seductive on "Mad Men," but Alexis Bledel will forever be thought of as the shy, bookish Rory Gilmore on "Gilmore Girls." Her performance on the show carried her into other Rory-like roles in the films "Sisterhood Of The Traveling Pants" and "Post Grad."

  • Tracy Morgan (Tracy Jordan), "30 Rock"

    Tracy Jordan is known for his outbursts and ridiculous adventures on NBC's "30 Rock." And as it turns out, Morgan isn't so different from his character -- he rarely thinks before he speaks and definitely lives each moment as if it's his last.

    Ron Swanson isn't the only one with a passion for woodworking. When he's not acting, <a href="http://www.huffingtonpost.com/2012/03/08/ron-swanson-parks-recreation_n_1326738.html" target="_hplink">Offerman is crafting aesthetically pleasing wooden objects</a> and his favorite magazine is <em>Fine Woodworking</em>. "Every year, they do an issue called 'Tools and Shops,'" he told HuffPost TV in March. "I read it like pornography.:

  • Blake Anderson (Blake), "Workaholics"

    Starring as a hard-partying 20-something on "Workaholics," Blake Anderson is equally as reckless. The actor ended up in the hospital in December after dunking a ping pong ball during a beer pong game, jumping from his roof and landing on his spine. Nice one!

  • Louis C.K. (Louie), "Louie"

    On the surface, Louis C.K. has a lot in common with his "Louie" character. They're both standup comedians with two daughters living in New York City. Still, we like to think of Louie as a dumbed down, sad sack version of Louis.

  • Larry David (Larry David), "Curb Your Enthusiasm"

    From saying whatever is on his mind to putting himself in the most awkward situations possible, it's no coincidence that Larry David's name is Larry David on "Curb." The line between the actor and his character is a blurry one!

  • Ricky Gervais (Ricky Gervais), "Life's Too Short."

    Known for making mildly offensive jokes almost constantly, Gervais appears as a version of himself in "Life's Too Short" alongside Warwick Davis, who works as a talent agent for little people.
