Ethan Hawke [1] enjoyed a fun-filled outing with his son, Levon Thurman-Hawke, in New York City on Sunday. The two were all smiles when they watched the New York Knicks take on the Brooklyn Nets at the Barclays Center in Brooklyn. The actor looked handsome in a blazer and ball cap, while his 15-year-old son, whom he shares with ex-wife Uma Thurman [2], kept things casual in a dark tee. While there's no denying that he takes after his mother, Levon certainly shares Ethan's smile.
