Dev Patel-
IMDB Page
The English-born Dev Patel is most well known for
Slumdog Millionaire (2008) in which he played the lead role. He is (also) 26 years old- young enough to pass for a young Maia. He could certainly portray a younger version of
Cliff Curtis, my nomination for
Manwe, as the two have already portrayed father and son in the movie
That Must Not Be Named.
Dev Patel also has a Black Belt in Taekwondo. And while Taekwondo practitioners do not train with weapons, it would be very cool to see Eonwe gettin' all fancy by combining martial art movements with various swords and spears and such. It was mentioned that Eonwe should look the most knight-like. A weapons-master would not need as much body mass as say a wrestler-type like Tulkas, but since knights are most closely associated with their armor, anybody can look tougher and bigger encased in metal. That might even be the best way to differentiate Eonwe 1.0 from Eonwe 2.0. For pictures of Dev Patel in (non-traditional) armor, reference the movie
That Must Not Be Named.
