The cable network announced Wednesday it has ordered eight episodes of the show, which Johnson will executive produce with his producing partner, Dany Garcia.
The series is set to premiere on TNT in summer 2013.
"'The Hero' will bring 10 ordinary people together in a house and then assign them various missions that will test their brains, their brawn and even their morality," a synopsis said. "The show will challenge the competitors to prove they've got what it takes to be heroes, pushing them to the limits to see what they are willing (and able) to overcome, undergo or sacrifice for the sake of their fellow contestants. Johnson will serve as 'The Hero's' mentor and motivator, encouraging the contestants to reach far beyond their personal limits."
"Dany and I couldn't be more excited to enter into our first official foray in TV production," Johnson said in a statement. "'The Hero' speaks to everything I believe in when it comes to challenging ourselves, to becoming better people every day and to making the right choices while growing from the wrong ones. Bridging the digital and physical world on the small screen in a way that's never been done before will enable fans to use social media and on-screen decision-making to determine the fate of the show's contestants, and our goal is to make each TV moment impactful and exciting."
