It seems that Kevin McKidd may no longer be the lead contender to play the titular god of thunder in Marvel Studio's Thor. A casting call that was snuck to Corona Coming Attractions has gone out for the lead in the film, and beyond simply confirming that McKidd is probably no longer up for the role, it also suggests what the producers and director Kenneth Branagh is looking for in the part.

The casting call reads:

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 severly humbled before becoming the compassionate, mature hero of our film.

According to the casting call, the start date for filming would be this July, with the film wrapping in September.
