The movie is a production of Michael Bay and Steven Spielberg through Dreamworks. The project is reported to have cost between $50 and $60 million. The plot is about an alien, human-like species that comes to Earth followed by another race, whose planet has been destroyed, who follows them to this planet. The first three have been killed and the character that Alex plays is number four. I've seen a past film that Alex Pettyfer starred in, Stormbreaker (2006) about spys and MI6 (UK), and found it interesting enough after seeing it in French to get a copy of my own even though its said to have been a flop.
I've long had a great interest in space, space exploration and sci-fi movies since the 1960s and plan to see this one. What about you? - V
