Casting for Thor

Coming Attractions has gotten a casting notice for Thor. This is what they're looking for:

Male MUST BE MID-LATE 20'S and SIX FEET OR TALLER. LEAD.

Physically powerful, very handsome, occasionally egotistical, petulant, and wild. A natural warrior with a quick charming wit who must be genuinely and severely humbled before becoming the compassionate, mature hero of our film.

A lot of people are kind worried about having a 25 year old actor playing Thor. You'd expect a god to be in their mid 30s. And also playing along side Robert Downey Jr. and Edward Norton in the eventual Avengers movie, a young Thor might seem a little out of place.
