Alex Pettyfer is on his way to becoming a huge star. The British stud shines in his role as John Smith aka Number 4 in the new Michael Bay produced action/sci-fi flick I Am Number Four. The film centers around Pettyfer's character, one of the nine chosen children from the planet Lorien, as he and his protector Henri (Timothy Olyphant) move from city to city in an attempt to avoid detection from the Mogadorians.
