Hawke has four children - 14-year-old Maya Ray and 11-year-old son Levon Roan from his marriage to ex-wife Uma Thurman, and daughters Clementine, aged four, and Indiana, nearly two, with his wife Ryan Shawhughes.
Fresh from the success of his latest movie The Purge, Hawke is about to reappear in Australian cinemas as recurrent character Jesse Wallace in Before Midnight, the follow up to 1995 cult hit Before Sunrise and 2004's Before Sunset.
Hawke is currently focusing on a return to Broadway where he will tread the boards as the Celtic King in Macbeth.
