Emmy winner Megan Mullally ('Will & Grace') will return to the NBC comedy 'Parks and Recreation,' reprising her role as Ron's (real-life husband Nick Offerman) ex-wife. "I'm doing one next week or the week after," she told the Ausiello Files, though no word on when the episode will air. For more on Mullally's return, check out her interview with TV Squad.

More casting news after the jump.

Over her nearly 25 years in the business, Gina Gershon has worn many hats.

Recently, she's been trying out her comedic chops with appearances on 'Curb Your Enthusiasm,' 'Ugly Betty' and 'Eastbound & Down.'

But this weekend, she'll take on quite a different role as the lead in the Liftetime two-part movie event, 'Ann Rule's Everything She Ever Wanted.' Gershon plays Pat Allanson, a privileged southern charmer who has a taste for the finer things in life -- and will stop at nothing to get them.

AOL TV recently spoke with Gershon about the miniseries, premiering Sun., Nov. 14 at 8PM.

The Costume: 'Eastbound and Down' former Major League Baseball pitching sensation Kenny Powers (played by the hilarious Danny McBride), who's still a legend in his own mind.

What You'll Need: Jeans, a T-shirt with the sleeves cut off, a beer can in one hand, a baseball glove on the other and facial hair manscaped into a circle beard. Essential to pulling off the Kenny Powers look: the perm/mullet wig, because Kenny is all about business up front and some serious, get-down-with-your-bad-self partying in the back. And by the way, we do mean wig, because we hope you're not trying to rock that look with your own hair.

Here are the highlights of this week's DVD releases. Enjoy!

'Entourage' (The Complete Fifth Season)

What This Season Is About: Vince (Adrian Grenier) and Turtle (Jerry Ferrara) are hiding out beachside in Mexico after the failure of 'Medellin.' Ari (Jeremy Piven) and Eric (Kevin Connolly) begin plotting Vince's rise back to the top, resulting in Vince getting cast in Martin Scorcese's version of 'The Great Gatsby.'

Why You Should Check It Out: Stellan Skarsgard, Jason Patric and Gus Van Sant guest star, as well as Jamie-Lynn Sigler, who plays herself in a recurring role as Turtle's new girlfriend.

I didn't expect to be charmed by a show about a dude who snorts blow off a loaded rifle.

HBO's Eastbound & Down turned out to be my favorite new comedy of the year. The show, produced by Will Ferrell and Adam McKay, seemed like a one-note joke at first. It stars Danny McBride as Kenny Powers, a deluded and self-obsessed former baseball star forced to move back to his hometown and work as a middle school gym coach.

Surprisingly, this thing got funnier and more addictive with every episode. Danny McBride is great as the extremely vulgar Kenny Powers, and the show has a lot more going for it than most of Ferrell and McKay's juvenile big screen comedies.

Eastbound & Down had an abbreviated first season – only six episodes – but HBO just renewed it for a second season.

'Big Love'
(Sun., 9PM, HBO) 3rd season finale
For three seasons, Bill Henrickson has struggled to break free from his past, namely dealings with prophet Roman and his plotting, thuggish in-laws, the Greenes.

Bill thinks he's finally found a way, via a legal ally, to rid himself of the whole bunch all at once, though, as always, Roman will be at his wily best when the heat is on.

Meanwhile, as Sarah finally settles on post-high school plans, Nicki has a surprise reunion, Alby struggles to hold on to control of the compound and one character – a major character – becomes the second shocking 'Big Love' death of the season.

What It's About: Kenny Powers (Danny McBride) is an ex-professional MLB closer who's gone from flame-throwing world series MVP to overweight, noodle-armed phys ed teacher. He's moved back to his hometown, where he's a big, inappropriate, vulgar fish in a small, moral North Carolina pond. Kenny battles with drug abuse, steroids -- and his own stupidity

The Buzz: Will Ferrell brings his raunch, over-the-top humor -- and love of sports comedies -- to the small screen. He teams with co- 'Anchorman' scribe Adam McKay, while McBride, who co-stars in Ferrell's upcoming 'Land of the Lost,' is one of the show's lead writers. Since it's on HBO, expect no-holds-barred crude comedy.

SHOWS TO KNOW

It looks like even the magic formula that Will Ferrell and Adam McKay created to become comedy movie mavericks doesn't work on the aptly named "idiot box."

HBO's new Eastbound & Down bombed in its premiere episode and lost nearly 40 percent of the lead-in audience from Flight of the Conchords. It also only scored a measly .3 in the ratings, which is dangerously close to "HelloLarrydom."

But fear not, Ferrell freaks. This is HBO, the network that dared to mess with convention, give fledgling shows time to grow and kept Arli$$ on the air for six whole seasons.

'Eastbound and Down'
(Sun., 10:30PM, HBO) series premiere
You probably know him from 'Pineapple Express' and 'Tropic Thunder' (or, for you indie film fans, 'The Foot Fist Way'), but wild and crazy character actor guy Danny McBride is headed to the small screen in this comedy from producers Will Ferrell and Adam McKay.

McBride is Major League Baseball pitcher Kenny Powers, whose loutish behavior on and off the field have led to his permanent ouster from the game.

And since he wasn't exactly a big saver he's dead broke his only option is to slink back to his North Carolina hometown, sponge off his brother and take a job as a gym teacher at his old junior high school.

Last September, Brett told you about a new HBO pilot being created for HBO called P.E. Well, that pilot is still happening, but now it's called East Bound and Down. The plot remains the same, though: a washed-up professional baseball player winds up back in his Southern hometown and becomes a substitute gym teacher.

The new comedy comes from actor Will Ferrell and his writing partner Adam McKay's Gary Sanchez Productions. The men previously worked on Saturday Night Live together and later on the films Anchorman and Talladega Nights. Newcomer Danny R. McBride (who also co-created the series and wrote the script along with Jody Hill and Ben Best) will star as Kenny, the pitiful pitcher, along with Katy Mixon, John Hawkes and Andrew Daly. Mixon plays Kenny's former high school girlfriend, who is now engaged to the principal (Andrew Daly). Kenny's brother will be played by Hawkes.
