Michael Rooney (b. 1962) choreographed and staged the new musical numbers in the 2011 feature film The Muppets. He appeared in the film as the Smalltown, USA butcher singing "life's a leg of lamb" during the "Life's a Happy Song" musical number. He later choreographed for the live stage shows The Muppets Take the Bowl and The Muppets Take the O2.
He is the son of Mickey Rooney, who had a cameo in one of the sequences choreographed by the younger Rooney. According to Jason Segel on the commentary for the Blu-ray release of The Muppets, Michael Rooney had been repeatedly calling Mickey Rooney "Dad" on set. Finally, Segel said, "You can't just call an old guy dad." Rooney replied, "No, that's my actual dad."
Rooney's other choreography credits include musical sequences in the films 500 Days of Summer and Clerks II, plus Dancing with the Stars. His work in countless music videos, commercials, and live stage appearances include collaborations with such performers as Kylie Minogue, Spice Girls, Bette Midler, Dolly Parton, Paula Abdul, and Michael Jackson.
