“Knock-Knock Live” is produced by Simon Fuller’s XIX Entertainment and Dick Clark Productions. Fuller, Michael Herwick, Allen Shapiro, Mike Mahan, Mark Bracco, Stijn Bakkers, Nicolle Yaron and Ryan Seacrest serve as executive producers. Fuller, Seacrest, DCP and Fox are stakeholders in the format worldwide. Fuller’s business XIX Entertainment has appointed DCP to be the international distributor of the format and series.
Posey’s MTV show is currently in its fifth season, and he can next be seen in Kevin Smith’s upcoming feature comedy, “Yoga Hosers.”
“Knock-Knock Live” debuts Tuesday, July 21 at 9 p.m. ET on Fox.
