In 'Earth to Echo,' a group of kids encounter alien life...and it’s totally adorable. This isn’t the first time something so fantastical has also been so darn huggable. Hollywood has a long history of cute robots, aliens and monsters, and here are some of our favorites.

Gizmo (Gremlins)

Here he is: the quintessential cutey movie creature. Smart, affectionate and totally loving, Gizmo is the ultimate pet. Just don’t let him get near any water...or feed him after midnight. He’s one error away from ruining your life!

E.T. (E.T.: The Extra-Terrestrial)

With his wrinkly, squashed face, E.T. is the alien equivalent of a pug. He’s weird looking, sure, but n a real lovable way. Plus, all he needs to survive is Reese’s Pieces and that’s so much cheaper than dog food.

Wall-E

Wall-E is so small, cute and endearing that he practically begs you to pick him up and squeeze him. But... uh, don’t do that. He’s a robot and he has pointy edges, Cuddle with care--and wear long sleeves!

Stitch (Lilo and Stitch)

Stitch is a wild and crazy alien with an appetite for destruction...which means he’s on the same level as your typical puppy. Once you get over the fact that he’s never going to stop biting, he’s a pretty great pet. Just stock up on teething toys!

The Fix-Its (Batteries Not Included)

The Fix-Its are living machines capable of doing incredible wonders with technology that is beyond our imagination. They're also super cute!

Minilla (Son of Godzilla)

Who knew  the vicious king of the monsters could produce such adorable offspring? Minilla may look like a small version of his father, but the spawn of Godzilla is perfectly tame.

Max and Puckmaren (Flight of the Navigator)

Here’s how adorable Trimaxion (aka Max) is: he's responsible for throwing a young kid’s life into total disarray and we still fall in love with him. Even cuter is the Puckmaren, which is like a bat injected with cuteness steroids.

Number 5 (Short Circuit)

What would Wall-E look like if he grew up? Number 5 isn’t as tiny and cuddly as other guys on this list, but his pure optimism and innocence is downright adorable. The rare laser-toting robot you’d actually want to hang around your children!

R2D2 (Star Wars)

Depending on the scene, R2D2 can seem like a small child or a whip-smart trained dog. But no matter the context, he’s as cute as robots come. If only our dogs and babies spoke in unassuming electronic beeps and boops...

Marvin (The Hitchhiker’s Guide to the Galaxy)

Marvin’s adorable design doesn’t hint at the depressed personality programmed into his brain. His large head and tiny body are so huggable, and his pessimistic disposition makes him a creature of pity. You just want to pick him up and tell him everything is going to be okay.

Bubo (Clash of the Titans)

Bubo contributes almost nothing to Perseus’ epic quest...but who cares? He’s the most adorable robotic owl to ever inexplicably show up in a tale inspired by Greek mythology. If Perseus is Luke Skywalker, Bubo is his winged, pocket-sized R2D2!

Bumblebee (Transformers)

When Bumblebee is on the attack, he’s as deadly a warrior as the rest of his Autobot brethren. But off the battlefield, he’s downright cuddly and as eager to please as a puppy.

Teddy  (A.I.: Artificial Intelligence)

Teddy is the science fiction equivalent of Eyeore. He’s a gloomy pessimist in the cutest body imaginable and he can’t help but be a downer in any given situation. Still, his undying companionship and totally cute face make a ray of cuteness in a movie that goes out of its way to not be cute!

The “Minors” (Galaxy Quest)

Some of the cutest movie creatures are also capable of tearing you limb from limb. These little guys are best observed from a distance. If you get too close, they may eat you.

The Chestburster (Alien)

When it grows up, the tiny Chestburster will bcome the ultimate killing machine. But when it’s a newborn, it’s just so tiny! And so cute! Look at it’s little face! Look at its little teeth! Never mind the blood...isn’t it precious?

The Critters

The Critters may not seem so cute upon first glance, but let’s look at the facts: Capable of sitting in the palm of your hand? Soft and furry? Yeah, never mind those razor sharp teeth--they’ve got what it takes.

Ewoks (Return of the Jedi)

Half teddy bear and half warrior, the Ewoks are easily the cutest creatures to ever help defeat an intergalactic empire of evil. Just don’t piss ‘em off -- they have the bad habit of trying to cook Jedi Knights and reformed smugglers.

The Iron Giant

He may tower above the forest, eat metal and be armed with enough weapons to wipe out the human race, but the Iron Giant is just a big sweetheart.
