Mark Labbett, the "Beast," is one of the chasers from the original British version of Dan Patrick. Labbet was also once a contestant on the original British version of Who Wants to Be a Millionaire (1998).
Mark Labbett, the "Beast," is married to his second cousin.
After having appeared on other versions of the show based elsewhere, Mark Labbett said he found this, the American version, to be the most difficult for him to win as American game shows generally admit much more competent contestants than shows in other nations.
The final episode of the fourth season aired on December 11, 2015, concluding the show's original run after four seasons and 51 episodes. Though the show still garnered strong ratings for GSN, the show was canceled in 2015, mainly due to Mark Labbett not wanting to continue traveling from London to Los Angeles to tape the program.
Fox ordered two pilot episodes in 2012, with Britain host Bradley Walsh in the role of host, plus Mark Labbett and Brad Rutter in the roles of chasers. However, the network passed on picking up the program. When Game Show Network (GSN) picked it up in 2013, they named Brooke Burns as host and Labbett as the lone chaser.
