A scene from The Jungle Book.

The Jungle Book, Disney’s latest live-action take on one of its animated classics, is clever: It actually contains sly nods to Apocalypse Now and Saturday Night Live.

Jon Favreau’s delightful and funny take on Rudyard Kipling’s tale of a boy raised by wolves is an all-around winner. Kids and adults will love the talking (and sporadically singing) animals, while adults and some of the cooler kids will enjoy the movie references and clever Easter eggs.

The story is pretty simple: A young boy, Mowgli (newcomer Neel Sethi), raised in the jungle, is pursued by a pissed-off tiger (the voice of Idris Elba) who had his face burned by a human when he was young (shades of Darth Vader). When plans to leave for a human village are rudely interrupted, Mowgli winds up staying in the jungle longer than he planned. He encounters Kaa (Scarlett Johansson), an evil temptress snake, and other perils while building a special friendship with a big bear.

As far as I could see, he never stops to wash his red shorts. A swim in the river doesn’t count. You need detergent.

Bill Murray is a masterstroke of vocal casting as Baloo, the big bear who befriends Mowgli on his extended jungle trek. But casting Christopher Walken as King Louie, the Kong-sized master of all apes, actually tops the Murray casting feat. It gives Favreau’s film an opportunity to become truly weird, very funny and even a little scary.

Favreau finds some clever ways to mix musical performances into the movie, even though it’s not a bona fide musical. Baloo and Mowgli happily sing part of “The Bare Necessities” together while floating down a river, accompanied by a full orchestra led by John Debney. It’s great, but it’s not the film’s musical highlight: That comes when Walken’s King Louie, portrayed with undertones of Brando’s Col. Kurtz, suddenly busts out “I Wanna Be Like You.” Walken is perfect for the song and perfect for the character, making the scene an instant classic. Johansson performs another song from the animated movie, “Trust in Me,” during the credits.

Incredible special effects seamlessly mesh with live animals, motion-capture work and puppetry. The talking animals actually look like they are really talking.

Other voices include Ben Kingsley as Bagheera, the panther who raised Mowgli, and Lupita Nyong’o as the wolf, Raksha, who acted as his mother figure. Giancarlo Esposito, aka Buggin’ Out, lends his chords for Akela, leader of the wolves, and Garry Shandling voices Ikki in what turned out to be his final film.

If you have a couple of extra bucks, shell out for the 3-D or, better yet, IMAX version of the movie. Favreau was very conscious of the technology, and he gives the movie some nice extra scope. Tree branches look like they are going to poke you in the face, and it almost seems as if Kaa might get you into her death coil. The 3-D also makes the pop-up-book end credits all the more fun.

It’s worth noting that the movie, which appears to be very outdoorsy, was filmed entirely on studio sets and made within computers. Every landscape you see is artificial, making the filmmaking achievement something of a miracle.

Sethi, the only live actor with a big part in the film, is good enough as Mowgli, although interest in his character’s plight is diminished by the fact that the film is so much cooler when the animals are at the center of the action.

Talks are under way for a Jungle Book 2 already, with Favreau returning, so the adventures of Mowgli look to be continued. Perhaps a main plot point could be Mowgli finding some new shorts or a bathing suit. He’s going to get a fungus in those red shorts!

Hopefully, Murray will get over his sequel stigma and be back as Baloo. And Walken … I gotta have more Walken!

The Jungle Book is playing at theaters across the valley in various formats.
