Rolling Stone has put together a list of the 21 Best Movie Sidekicks.  They include Chewbacca, Robin, Mimi-Me and even Donkey from Shrek.

Here are few in no particular order:

Chewbacca (Star Wars)

Princess Leia dissed him as a "walking carpet," but Han Solo's wookiee co-pilot is everyone's favorite sidekick. As played by Peter Mayhew throughout the Star Wars saga, Chewie is more than seven feet tall, strong, silent (well, not silent, but unintelligible), loyal, hypercompetent, fearless, and well-accessorized with that bandolier. Even Leia came to rely on him as indispensible to the rebels' cause. He was unjustly denied a medal at that ceremony at the end of Star Wars: Episode IV – A New Hope, but maybe he'll settle for being named King of the Sidekicks.

Samwise Gamgee (Lord of the Rings)

The indomitable, almost insane perseverance that Sean Astin brought to Rudy is present in his Lord of the Rings hobbit, too. No matter what happens, he won't let Frodo (Elijah Wood) get lost, either geographically or spiritually, on his way to Mordor to destroy the corrupting ring of power and save Middle-earth. As Sam tells Frodo, in the most moving moment in the trilogy, he can't carry his master's burden, "but I can carry you."

Dr. John Watson (Sherlock Holmes)

In the Sherlock Holmes stories, Watson has always been the audience stand-in, the translator who explains to us regular folk the eccentric, inscrutable, brilliant mind of the world's greatest sleuth. He's been played by such venerable actors as Robert Duvall and James Mason, but in the current Holmes movies, Watson is a young, vigorous Jude Law. For once, Watson isn't just the only guy who understands Holmes (Robert Downey Jr.), but also the only one who can keep up with him in the franchise's action set-pieces.

Goose (Top Gun)

Sometimes the sidekick has to take one for the team. In Top Gun, Anthony Edwards' Goose is Maverick's (Tom Cruise) ideal wingman, drinking buddy and fighter-jet support. But it's his death in the line of duty, in a freak jetwash accident, that spurs the grief-stricken Maverick toward greatness and destiny.

Hit-Girl (Kick-Ass)

Hit-Girl (Chloe Grace Moretz) was bred to be a sidekick. Her self-styled superhero dad, the Batman-esque Big Daddy (Nicolas Cage), taught her everything he knew about weapons and martial arts. Once he fell, it was not hard for her to become sidekick to another self-styled superhero, Kick-Ass (Aaron Taylor-Johnson). Then again, Moretz was so charismatic as the pint-sized, foul-mouthed, bone-crunching 11-year-old that many moviegoers thought she stole Kick-Ass from its title character. With Kick-Ass 2 due in August, we'll see if the balance of power has shifted.

 Robin (Batman)

Most superheroes are loners, and indeed, Robin sometimes seems more trouble than he's worth to Batman. As played by Burt Ward in 1966's Batman (essentially, a supersized episode of the campy ABC TV series), he's full of gee-whiz earnestness, but he's also a magnet for any supervillain who wants a hostage in order to extort the Caped Crusader. Chris O'Donnell, in Batman Forever and Batman and Robin, has acrobatic skills, but he's also an annoying, snotty pup. At least the putative Robin (Joseph Gordon-Levitt) in The Dark Knight Rises is discreet enough to stay out of Batman's way. An orphan, he understands Batman's sense of mission as well as anyone, and he proves a worthy heir to Batman's legacy. Given how many Batman tales suggest an aging hero who's contemplating hanging up the cowl before he gets himself killed, heir apparent seems the most fitting role of all for any Robin.

Cameron Frye (Ferris Bueller's Day Off)

Perpetually truant high schooler Ferris Bueller (Matthew Broderick) can always count on the morose Cameron (Alan Ruck) to accompany him on his misadventures, impersonate Ferris' girlfriend's father on phone calls to the school principal, and even purloin that awesome Ferrari of Mr. Frye's for a joyride into downtown Chicago. Ferris may be exploiting Cameron's spinelessness, but he's also doing him a big favor, not just forcing Cameron to stand up to his neglectful dad, but also giving him a day of fun in the hope of elevating him out of what may be a suicidal depression. Who knows what happens after the end of Ferris Bueller's Day Off, but let's hope the gangly guy in the Detroit Red Wings jersey is inspired to fly on his own.

Donkey (Shrek)

Puss in Boots is too self-reliant and narcissistic to be a good sidekick to Shrek, but Donkey (Eddie Murphy) is so loyal to the ogre that he's practically co-dependent. He doesn't even have a distinctive name to suggest a unique identity. His friendship is unconditional, and he always has Shrek's back, no matter what kind of peril the two encounter in their world of grim fairy tales. That he won't ever stop yammering seems a small price to pay.
