In the unlikely event that you haven't heart of Domhnall Gleeson already, 2015 is the year when that's all about to change. The 31 year old son of acting legend Brendan Gleeson is going to be taking on a role in Star Wars Episode VII The Force Awakens in December 2015, and you don't get much bigger than that.
Right now though he's working up an impressive acting resume by starring in Alex Garland's Ex Machina - a tale of technology and morality which is one of the best sci-fi offerings of the year. It's the first feature film as director for Garland and a sign that he's going to excel in yet another field.
In case you don't know Gleeson has also tried his hand at filmmaking, with a couple of shorts including this 2010 effort starring brothe Brian and dad Brendan.
