Zoe Saldana, Chris Pratt, Vin Diesel (voice) and Dave Bautista in Guardians of the Galaxy.

Guardians of the Galaxy is a goofy, dazzling and often hilarious convergence of inspired nuttiness.

You’ll probably hear comparisons to the original Star Wars, The Fifth Element and The Adventures of Buckaroo Banzai Across the Eighth Dimension; all of those comparisons are plausible. Guardians marks a blessedly new and crazy direction for the Marvel universe, and director James Gunn (Super, Slither) has taken a huge step toward the A-list.

Also taking a giant leap toward the upper echelon of Hollywood royalty is Chris Pratt, who mixes great charm, action-hero bravado and premium comic timing as Peter Quill, aka Star-Lord. After a prologue that shows the Earthly origins of his character, Pratt sets the tone for the movie during the opening credits, grooving to his cassette-playing Sony Walkman on an alien planet and using squirrelly little critters as stand-in microphones.

After unknowingly stealing a relic that could have the power to take down the entire universe, Quill finds himself in serious trouble. Events lead to his joining forces with a genetically enhanced raccoon named Rocket (the voice of Bradley Cooper), a gigantic tree-person thing named Groot (the voice of Vin Diesel), a muscle-bound angry alien named Drax (Dave Bautista) and an ass-kicking green woman named Gamora (Zoe Saldana).

Together, they become the Guardians of the Galaxy, an unlikely troupe of mischievous outcasts that plays like the Avengers met the Marx Brothers—if the Marx Brothers had a green sister. It’s a decent comparison. Quill is Groucho; Rocket is Chico; and Groot is Harpo. (He only has one line, “I am Groot!” while Harpo only had the honking horn.) I’d say Gamora is Zeppo, but that would be insulting to Gamora.

The cast, buoyed by a spirited script co-written by Gunn, keeps things zippy and always funny. Visually, the movie is a tremendous feat. If you see it in 3-D, you will be happy with the results, because every shot seems meticulously constructed to benefit the medium. As for the makeup, just as much energy has been put into the practical effects as the digital work.

Michael Rooker, playing bad-guy Yondu, looks especially cool with his blue skin and ragged yellow teeth. Josh Brolin shows up briefly as Thanos, a major villain in the Marvel universe, while John C. Reilly, Djimon Hounsou, Glenn Close and Benicio Del Toro are along for the ride.

With her presence here, and her work Star Trek and Avatar, Saldana has officially inherited the Queen of Science Fiction mantle from Sigourney Weaver (and she’s incredibly hot when she’s blue or green). Pratt establishes his leading-man status here, something that could be fully cemented with his turn in the Jurassic Park sequel next year.

While Guardians is a terrific visual spectacle, it also packs an emotional punch. Rocket delivers a speech about alienation that is far more moving than anything you’d expect to see in a movie like this, while Quill’s mommy issues fuel some surprising emotional moments. The cast does some real acting; Cooper’s feat is especially impressive, since we only hear his voice. Heck, even Vin Diesel packs a sentimental punch in the many ways he delivers his “I am Groot!” line.

The use of classic rock on the soundtrack is a brilliant touch. Quill’s old-school Walkman, still working decades after he left Earth, churns out the hits like “Hooked on a Feeling,” “Moonage Daydream” and “Cherry Bomb.” Like Wes Anderson and Martin Scorsese, Gunn is quite adept at using great music in unexpected places.

Guardians of the Galaxy rivals Edge of Tomorrow and Godzilla as this summer’s best blockbusters. As for its place in the Marvel universe, I’ll put it right alongside The Avengers as the franchise’s best.

Good news:  A sequel has already been green-lit for 2017, so this blissfully bizarre story shall continue.

Guardians of the Galaxy opens Thursday night, July 31, at theaters across the valley.
