Here’s the official synopsis:

“Join the wildest wedding party of the year when Bridesmaids marches down the aisle to Blu-ray, DVD and digital download on September 20, 2011, from Universal Studios Home Entertainment. Hailed as “brazenly hysterical” by People Magazine and “the best comedy of 2011” (Back Stage), Bridesmaids is the riotously funny and warmly outrageous comedy that has become the most talked about movie of the year. Critically acclaimed by fans and media alike, the “certified fresh” film (Rotten Tomatoes.com) received “two thumbs up! ” from Ebert Presents. Surpassing Sex and the City as the number one R-rated female comedy of all time, Bridesmaids starring “Saturday Night Live” standouts Kristen Wiig and Maya Rudolph, is produced by comedy mastermind Judd Apatow (Knocked Up, The 40-Year Old Virgin) and marks his most successful film ever.”
