Murphy enjoys playing 'badass' 75-year-old

Cillian Murphy found it a "nice challenge" to portray a 75-year-old man in movie 'In Time'.

The 35-year-old actor stars as veteran timekeeper Raymond Leon in the film, which sees his alter-ego on the trail of Will Salas – who is portrayed by Justin Timberlake – and his hostage Sylvia Weis (Amanda Seyfried).
