Max Irons received acclaim for playing Amanda Seyfried's love interest in the thriller, but rather than capitalise on his fame, the 25 year old is keen to remain out of the spotlight.
And his father is delighted at Max's decision, as he worries about the effect Hollywood will have on his son.
Jeremy Irons tells Britain's The Sun, ""My heart is in my mouth for him. Today it's 'grab 'em and spit 'em out'. In my day it was like that for girls but it now seems the same for boys.
""The business is difficult. There are so many good actors. Max has done two good plays but hasn't had the luxury I had of churning out stuff in rep (repertory theatre) and failing privately. He's looking for theatre stuff where he can be out of the limelight.""
