Ethan Hawke just won the ten-year challenge with this epic Boyhood throwback.
The 48-year-old actor is the latest celebrity to partake in the #10YearChallenge, which includes comparing an old and current photo on social media. Hawke shared a side-by-side pic with his former Boyhood co-stars Ellar Coltrane and Lorelei Linklater, and the straight-from-the-screen transformation is priceless.
