That was over 40 years ago in 1981.
Today he is 60, and has starred in 71 movies in total, 70 since Atlantic City was released.
In Atlantic City, I think Elias Koteas looks:
Atlantic City scores 6.8 out of 10 on The Movie Database.
Elias Koteas' first acting role was as 'Extra (uncredited)' in Atlantic City, released in 1981 when he was 20.
