It's hard to imagine anyone other than Chris Hemsworth playing Thor, the God of Thunder.
As it turns out, an unlikely star was in early talks for the role — one that Grey's Anatomy fans will recognise.
Kevin McKidd, who plays Owen Hunt in the popular series, was considered to pick up Thor's magical hammer before Hemsworth was cast for the role.
The co-founder of Marvel Studios' visual development department, Charlie Wen, shared the Hollywood tidbit in an Instagram post showing early concept art for Thor.
