Entertainment Weekly has debuted first look at Disney's upcoming sci-fi/fantasy adventure film Tomorrowland. The slightly-less-mysterious feature film is directed by Brad Bird (The Incredibles, Mission: Impossible -- Ghost Protocol) from a screenplay by Damon Lindelof and Jeff "Doc" Jensen.

"We begin our movie asking what did [the future] used to be?" Bird says. "What's good about the future and what's scary about it? And we wrestle with those things in a slightly mythical way."

In Tomorrowland, a Florida girl named Casey Newton -- played by Under the Dome's Britt Robertson -- who spends her spare time watching Cape Canaveral's launchpads finds a mysterious pin that, when touched, reveals images from a possibly better world. Lindelof cites the NASA's closed doors as the impetus for her adventure.

"It's closed for business," says Lindelof. "There are no launches anymore. But she still holds a candle, she still believes in this amazing future, that things can be better."

The discovery of the pin leads Newton's character to Frank Walker, a failed inventor played by George Clooney. "There's something about George," Bird says. "You can see the wheels turning in his eyes, and he reads as somebody who is very principled. He seems like a very pragmatic guy who also dreams, but he's not flighty. There's an integrity to him that you feel."

The film shares a name with a popular Disney attraction, but that's not the only connection the film has to Walt Disney.

"What Hogwarts is to magic, Tomorrowland is to science: They are both easy to find if you are a wizard and very difficult to find if you're a Muggle," says Lindelof. "Walt Disney is not a character in our movie, but he is referenced as having some involvement in this mysterious place called Tomorrowland, as a huge futurist and aficionado of space travel, rocketry, cities of the future, and space travel."

Tomorrowland opens on May 22, 2015.
