As Entourage's Vincent Chase (Adrian Grenier) and crew make the leap from cable TV to the silver screen, we look back at some classic movie entourages, from comedy slobs to sci-fi heroes. See them all in our gallery.

Few movies are as bro-ish as Entourage. This is one of them. Jon Favreau (who wrote the script) leads a group of struggling actor dudes in 1990s Hollywood. A skinny Vince Vaughn walks away with the movie as the oh-so-money Trent.

Justin Bartha plays the groom in this bachelor-party saga, yet he’s AWOL for much of The Hangover, leaving us with the awesomely cringe-worthy shenanigans of groomsmen Bradley Cooper, Ed Helms and Zach Galifianakis.

Knocked Up is first and foremost a rom-com. At its heart, though, it’s also about Seth Rogen and his hilarious hangers-on, all Judd Apatow discoveries: Jason Segel, Jonah Hill, Jay Baruchel, Martin Starr and Charlyne Yi.

Sure, Frank Sinatra led the Rat Pack in the original 1960 Ocean's Eleven, but George Clooney is so cool as Danny Ocean that even Brad Pitt and Matt Damon are willing to play second fiddle to him.

There’s never been a more unflappable bride than Maya Rudolph – even when she's pooping in the street. No wonder Kristen Wiig, Melissa McCarthy and the other great Bridesmaids cast members will do anything for her.

Entourage was inspired by executive producer Mark Wahlberg's own showbiz experiences. As porn star Dirk Diggler, Wahlberg’s on-screen entourage includes Don Cheadle, John C. Reilly, Julianne Moore and Philip Seymour Hoffman.

Usually, Will Ferrell gets just one good comic foil in a movie. In Anchorman he gets four: Christina Applegate, Paul Rudd, David Koechner and scene-stealer Steve Carell. Add a slew of cameos and you've got a comedy as classy as San Diego.

There's not much to laugh at in Christopher Nolan's mind-bender, but you can't beat Leonardo DiCaprio's dream team: Joseph Gordon-Levitt, Tom Hardy, Ellen Page, Ken Watanabe, Dileep Rao and, providing remote backup, Michael Caine.

On paper, the Ghostbusters are all equals. But let's be honest: as wonderful as Dan Aykroyd, Harold Ramis and Ernie Hudson (and Sigourney Weaver and Rick Moranis and Annie Potts) are, what would this movie be without Bill Murray?

Bill Murray again. Whereas director Wes Anderson's movies are all ensemble pieces, here he gives his title character (Murray) a genuine posse: Owen Wilson, Cate Blanchett, Anjelica Huston, Willem Dafoe...

Ghostbusters star Sigourney Weaver gets her own kick-ass backup in James Cameron's sci-fi actioner, from Bill "Game over, man!" Paxton to android Lance Henriksen to tough-as-nails Michael Biehn and Jenette Goldstein.

Who would deny that J.R.R. Tolkien's iconic fellowship – eight of Middle-earth's finest helping Frodo Baggins (Elijah Wood) bring the One Ring to Mount Doom – is the ultimate entourage story? Not us.
