The well-known Irish film director and author Simon Fitzmaurice has died at the age of 43.
Fitzmaurice, who was in his early forties, directed two shorts, including one which was nominated at the Sundance Film Festival.
He was diagnosed with motor neuron disease in 2008 and given four years to live.
Fitzmaurice wrote the bestselling book It's Not Yet Dark, which described his battle with the disease and was adapted into a feature film this year. It was directed by Frankie Fenton and narrated by Colin Farrell.
He went on to direct the movie My Name Is Emily which was released in 2015 and was nominated for eight IFTA awards.
He is survived by his wife Ruth and five children.
Tributes to the late author and director have been flooding in on Twitter with people hailing his "passion and creativity".
