Having previously brought Graham Greene’s 1938 novel Brighton Rock to life, Rowan Joffé is no stranger to book-to-film adaptations. He’s chosen a more contemporary work to bring to the big screen this time round in SJ Watson’s bestseller Before I Go To Sleep. Just as in the novel, the film focuses on an amnesiac who wakes up every day with no memory.

We were lucky enough to chat with the writer/director ahead of the film’s UK release, and in addition to divulging what his first movie memory was Joffé tells us about the challenges of adapting the novel into a screenplay and what other books he’d like to see get the big screen treatment. Have a watch below.

Before I Go To Sleep is in UK cinemas now.
