Liv Tyler turns 31 today and Marton Csokas’ birthday was yesterday; he turned 42. Liv, who has been acting in films since the early 90s, graced the screen as Arwen in all three Lord of the Rings movies. Her latest role was that of Betty Ross in The Incredible Hulk which opened in U.S. theaters on June 13. Marton, who played the lord of Lothlorien, Celeborn, in The Fellowship of the Ring, has enjoyed a long and successful film career in New Zealand and internationally and was last seen in Romulus my Father, released in Australia in 2007. Many happy returns to both of these fine actors!
