On the DVD commentary, Boyle explains that with the aim of preserving the [[suspension of disbelief]], relatively unknown actors were cast in the film. Cillian Murphy had starred primarily in small independent films, while Naomie Harris had acted on British television as a child, and Megan Burns had only one previous film credit. However, Christopher Eccleston and Brendan Gleeson were well-known [[character actor]]s.
