Here are this week's hottest home video releases:
Dwayne Johnson and Zac Efron show off both their action and comedy chops in this winning revival of the cheesy 1990s TV melodrama about crime-solving lifeguards. The film shamelessly mocks the original -- and series star David Hasselhoff pops up to join in on the fun -- to funny and exciting effect. The chemistry between Johnson and Efron keeps a limp plot afloat. Spotlights on stunts, training and the series' legacy, as well as deleted scenes, fill out the slate of special features.
Batman and Harley Quinn
Kevin Conroy returns as the voice of the Dark Knight in this animated team-up with Nightwing. The heroes are forced into an uneasy truce with the supposedly reformed Harley Quinn to face off with the combined threat of Poison Ivy and the Floronic Man, who aim to unleash a deadly virus. Sly dialogue and pop culture references abound, melding with superb action for yet another DC animation ace. Extras include a look at Harley Quinn's history, cast interviews and a pair of classic "Batman: The Animated Series" episodes featuring Harley Quinn.
Disneynature Born in China
A skilled achievement in cinematography and nature observation, this documentary takes a deep dive into the complex, interconnected ecosystem of the vast Chinese wilderness. Pandas, monkeys and snow leopards take center stage, with John Krasinski spinning the footage into heart-melting tales with charming narration. Extras highlight Disney's conservation efforts, behind-the-scenes action and a music video.
The Lion King: Walt Disney Signature Collection Blu-ray
One of Disney's greatest modern animated achievements gets another go-round on Blu-ray, this time bringing in tow a digital copy of the 1994 masterpiece about a lion cub's tale of redemption. Extras highlight the legacy of the film, including the Broadway musical adaptation and the upcoming live-action remake. Filmmaker commentary, a sing-along version, cast interviews and exhaustive looks at the making of the film fill out a loaded slate of extras.
