Irish author Claire Keegan has already enjoyed enormous success with the film adaptation of her novel 'Foster', in the form of 'An Cailín Ciúin'.

Now, a second adaptation of one of the Wicklow-born writer's books is set to hit the big screen - and with a big name in the lead role.

Cillian Murphy is heading up the cast for Keegan's 2021 novel 'Small Things Like These', which is set in Ireland at Christmas in 1985. Murphy's character Bill discovers that the convent in his town is holding some shocking secrets - as well as discovering some surprising truths about his own life.

Murphy - who will next be seen on the big screen in Christopher Nolan's 'Oppenheimer' this summer - is also producing the film, which is being financed by Matt Damon and Ben Affleck's company Artists Equity.

Enda Walsh wrote the script and it will also star Emily Watson and Ciaran Hinds.

Murphy said: "I’m honoured and thrilled to have the opportunity to bring Claire Keegan’s magnificent novel to the screen. We have gathered together a phenomenal team of creatives to make this film, and found exceptional partners in AE, a studio led by Matt Damon and Ben Affleck - actors and filmmakers I have admired for many years."

Filming is already underway in Ireland.
