Neil Patrick Harris, Michael Buble, Piers Morgan and Marlon Wayans to Guest Judge ‘America’s Got Talent’

Foursome will help Howard Stern, Heidi Klum, Mel B and Howie Mandel pick 36 acts for live performance shows

Neil Patrick Harris, Michael Bublé, Piers Morgan and Marlon Wayans are set to serve as guest judges on NBC’s “America’s Got Talent” this summer, joining full-timers Howard Stern, Heidi Klum, Mel B and Howie Mandel to help whittle the acts down to 36.

The four-week long judge cuts will premiere on July 14 (8-10 p.m. ET) and will lead into the live Radio City Music Hall performance shows beginning Aug. 11 (8-10 p.m.).

The guest judges, who will join the regular panel one at a time for a week apiece, will also be able to use the Golden Buzzer for their favorite act, sending them to Radio City Music Hall without any consultation from the “AGT” judges. Morgan is perhaps best-known to American audiences for being a former judge on”AGT” before hosting his own CNN talk show, which was canceled last year.

The only competition show open to all ages and all talents, “AGT” is hosted by Nick Cannon. Last season, magician and Rhode Island native Mat Franco won. Franco, who will headline a show at the LINQ Hotel & Casino in Las Vegas starting in August, was the first trickster to top the competition, and is set to star in two NBC primetime specials this summer.

“America’s Got Talent” is produced by FremantleMedia North America and Syco Entertainment. Simon Cowell, Sam Donnelly, Jason Raff, Trish Kinane and Richard Wallace are the executive producers.

The “Got Talent” format, co-owned by Syco Entertainment and FremantleMedia, holds the Guinness World Records title for the Most Successful TV Format in History, having been commissioned in 66 territories worldwide. “America’s Got Talent” also airs in 193 countries around the globe and has been the No. 1 U.S. summer reality series for the past decade.
