New on DVD: (Almost) All-Singing, All-Dancing!

And a 5-6-7-8: Mamma Mia! premieres on DVD Tuesday, but it's just one of three new gay-inclusive musicals hitting video store shelves.

Tune up on all the new releases after the jump.

One of the summer's surprise box-office smashes, Mamma Mia! vaults to DVD this week. Meryl Streep stars as a former singing sensation who's about to marry off her daughter (Big Love's Amanda Seyfried). The bride creates chaos by inviting three of mom's old suitors (Pierce Brosnan, Colin Firth, Stellan Skarsgård) to the wedding on the assumption that one of them has to be her father.

Not that audiences particularly cared about the plot—it's the 22 ABBA songs that packed houses for the movie (like the stage show before it) and viewers at home can harmonize along on "Take a Chance on Me" and all the rest thanks to the DVD's sing-along features. (Odds are, you're a better singer than Brosnan.)

Even with an out-of-left-field gay reveal (spoiler), queer audiences ate this one up with a spoon and will no doubt run out to snatch up the DVD for the deleted scene of Dominic Cooper baring his beach bum.

If you're not so much into ABBA and maybe prefer your musicals with a little more intentional comedy, you've got two other terrific options. Dr. Horrible's Sing-Along Blog, which began life as a web series, comes to home video Friday and even features what may be the very first singing commentary. Created by Joss Whedon (Buffy, Angel, Firefly), Blog tells the tuneful story of lovesick would-be super-villain Dr. H (played by gay icon Neil Patrick Harris) and how he finds himself cockblocked by an obnoxious superhero (Nathan Fillion) when both of them fall for the same girl.

Also new to DVD is Hamlet 2, gay director Andrew Fleming's hilarious portrait of a manic high-school theater director (Steve Coogan) who tries to save his job by staging a musical sequel to the most famous play in the English language (read our positive review).

Ditties like "Rock Me Sexy Jesus" and "Raped in the Face" will have you screaming with laughter as you tap your toes, and the film makes great use of gay men's choruses and closeted drama club boys, to say nothing of its hilarious supporting cast (including Catherine Keener, Amy Poehler and, as an alternate-universe version of herself, Elisabeth Shue).

If all that weren't enough music, gay-vague musician Mika releases his new live DVD, Mika Live au Parc des Princes. He never quite caught on in the U.S. after the success of his debut single "Grace Kelly," but heaven knows gay music fans are the most steadfast in the world; whether or not he ever breaks out in this country, there will always be a cadre of devoted queer followers here to snatch up his every new release.

Meanwhile, in the non-singing world, the somewhat ill-considered remake of The Women comes out this week as well. While Diane English's reimagining of the classic Clare Boothe Luce play won't make anyone forget gay director George Cukor's 1939 classic, it does provide for a neat little film history asterisk: Meg Ryan and Candice Bergen play daughter and mother in the film; Ryan's screen debut was playing Bergen's daughter in Rich and Famous, which was ... wait for it ... Cukor's last movie.

Picture This! keeps coming up with enough short films about adorable shirtless boys to make compilations, and here comes Boys' Briefs 5: Schoolboys. While shorts don't get much of a life outside of festivals, they often are where the feature directors of tomorrow get their feet wet behind the camera. Who knows if any of the filmmakers featured here will go on to bigger and better things? Start checking out these comps now so you can be way ahead of your friends when it comes to spotting the hot new directors.
