'The Space Between Us' Trailer Features First Human Born on Mars and His Love Story

The boy travels to Earth to seek out a girl he met online.

In The Space Between Us, Gardner Elliot (Asa Butterfield) plays the first human born on Mars after a team of astronauts visit the planet in order to colonize it. At age 16, he travels to Earth for the first time and seeks out Tulsa (Britt Robertson), a girl he met online while living on Mars.

"Tell me where you're really from," says Tulsa in the first trailer for the movie. "Mars," responds Gardner, adding, "Just because something sounds crazy doesn't mean it's not true."

The problem is, Gardner's heart can't handle Earth's gravity and Gary Oldman's and Carla Gugino's characters seek out Gardner while he is on his adventure. In the trailer, the audience learns that Gardner's birth is classified and kept a secret. As a result, he grows up having only met 14 people. Once he reaches Earth, he is fascinated by the colors around him, scared by a horse and delighted by rain.

Peter Chelsom directs the sci-fi film, which hits theaters Aug. 19.
