Which actress played the lead role in the 2011 film 'Bridesmaids'?

Kristen Wiig played the lead role in the 2011 film “Bridesmaids.” She portrayed Annie Walker, a woman whose life becomes increasingly chaotic after she is asked to serve as maid of honor for her best friend, Lillian, played by Maya Rudolph.

Wiig also co-wrote the screenplay with Annie Mumolo. The idea developed after producer Judd Apatow saw Wiig's comedic talent in “Knocked Up” and encouraged her to develop a film concept. Director Paul Feig later brought the script to the screen, combining relationship comedy with an ensemble cast.

“Bridesmaids” also featured Rose Byrne, Wendi McLendon-Covey, Ellie Kemper and Melissa McCarthy. McCarthy's performance as Megan earned an Academy Award nomination for Best Supporting Actress, while Wiig and Mumolo were nominated for Best Original Screenplay.

A common mix-up is choosing McCarthy because her performance became one of the film's most memorable. However, McCarthy played a supporting character; Wiig was the central performer and also played Annie, the film's protagonist.
