Asa Butterfield is the boy who is literally not from this planet. That is the ultimate fish out of water scenario for a human character. And then he’s travelled all the way from Mars to meet the only girl he loves/knows. There is sufficient promise in the premise as well as the trailer.
Who knows what the movie will be like.
The movie also stars Gary Oldman, Carla Gugino, BD Wong, and Britt Robertson.
