Dwayne Johnson hosts "Rock and a Hard Place"

The Rock's new recipe: The Rock is cooking something, but it isn't a ringside punch or a fast and furious car: it's hard work, tough love and justice all rolled into one. Dwayne Johnson, known as "The Rock" in his professional wrestling career, is the host of "Rock and a Hard Place," a new documentary premiering Monday, March 27, on HBO.

He's living up to his stage name. In the doc, a group of young inmates from a Miami detention facility is given a choice between passing a six-month rehabilitation boot camp under his tutelage or serving out their lengthy prison sentences.

It's the same mix of structure, hard work and strict discipline that Johnson credits with helping him out in his own youth. "I know this boot camp program, and I believe in it," he says to an assembled group of prisoners in a preview of the special. The prisoners who are part of the program need to prove that they're able to put their lives of crime behind them, or else they earn themselves a one-way ticket back to the slammer.

Beyond the wrestling ring, from which he is semi-retired, Johnson's acting career has grown into a huge success for both him and the films in which he's starred. His first blockbuster role was that of the villainous Scorpion King in "The Mummy Returns" (2001), but that was only the beginning for the wrestler-turned-actor. That role was followed up with a long chain of hits, including the spinoff "The Scorpion King" (2002), "Walking Tall" (2004) and "Doom" (2005).

He joined the ensemble cast of the The Fast and the Furious franchise with "Fast Five" (2011), which had the biggest opening weekend for the franchise up until that time. It's not all fast cars and murderous mummies, though; Johnson's also starred in plenty of family fare, including "Tooth Fairy" (2010) and last year's animated hit "Moana."

The Rock has been cooking up a successful acting career, but he also wants to help turn bad guys good. "Rock and a Hard Place" premieres Monday, March 27, on HBO.

Some human castings: Marvel's "Inhumans" cast is growing. Anson Mount ("Hell on Wheels") and Serinda Swan ("Graceland") headline the cast of ABC's new superhero show about a group of superhumans born with incredible powers. In a blockbuster deal with IMAX, the first two hours of "Inhumans" is set to premiere in 1,000 IMAX theaters over Labor Day weekend before moving to TV screens following a two-week theatrical run.

Mount stars as Black Bolt, the king of the Inhumans, who possesses a voice that carries so much power that he cannot speak -- even a whisper could level whole cities. Swan stars as Black Bolt's queen and most trusted adviser, Medusa, who has the ability to control her hair with the same dexterity that ordinary people control their hands.

Ken Leung ("The Night Shift"), Isabelle Cornish ("Home and Away"), Eme Ikwuakor ("Ink," 2009) and Mike Moh ("Empire") have been cast as the remaining members of Black Bolt's royal family of Inhumans, with Ellen Woglom ("Californication") and Sonya Balmores ("Beyond the Break") rounding out the main cast.

Black Bolt and the Inhumans, who were created by comic book legends Stan Lee and Jack Kirby, made their first appearance in Marvel comics in 1965. Until now, they've only had cameos in other superhero series, but come September, this loved group of super-powerful superhumans will finally have a major feature to call their own.

Game on: Ellen DeGeneres is moving in on prime time. The comedian's syndicated talk show, "The Ellen DeGeneres Show," is known for the off-the-wall games that it plops its audience members into, and now, DeGeneres and NBC are teaming up to give those games their own home.

"Ellen's Game of Games" has been given a six-episode order at the peacock network, with no release date yet set. 

Every hour-long episode will borrow heavily from the games that have been honed over the years on DeGeneres's talk show, supersizing them for a full game show format while also coming up with some entirely new and unique ideas.

"I'm so excited to be hosting a huge prime-time game show for NBC," DeGeneres said in a statement. "We're pulling out all the stops -- gigantic sets, hilarious games. It's going to be like a combination of 'American Ninja Warrior,' 'RuPaul's Drag Race' and a water park. OK, it's nothing like that, but you should still watch."

Some of the games that frequently pop up in "The Ellen DeGeneres Show" include "Make It Rain," "What's in the Box?" and "5 Second Rule," although there's been no word on which of them will make the transition to "Ellen's Game of Games."
