I'm looking for a title of a movie I saw last year. I don't really know when it was made but it's not that old. I only remember that it was about a brother and a sister. They where at the beach and the girl finds a teddy bear or something similar. The teddy talks to her but no one else can hear it. The teddy was on a mission and I think he was from outerspace. And the kids is going to take him back to where he come from. Someone who know what movie it is?

The Last Mimzy (2007) (http://www.imdb.com/title/tt0768212/)

Thank you :D
