Milonakis was born with a congenital disorder that causes growth hormone deficiency, causing him to appear to be very young.

So far he has not been cast in any serious films, but he was cast in several teenager-oriented feature films (Waiting…, Still Waiting…, Extreme Movie, Who Is Your Caddy?) alongside some rising stars Ryan Reynolds, Anna Farris, Justin Long, John Michael Higgins, Matthew Lillard and Michael Cera.
