Late yesterday word came out the McKidd wasn't even aware of this until he asked his agent about it after hearing the rumors (ain't the internet great?). However the news isn't quite what we expected to hear...
"I didn't know about it either until I heard the rumors and I called my agent, and he went, 'Yeah, yeah, yeah, we've been talking to them about it.' But the last I heard from my agent, they're talking that they want to go for somebody much younger, a 19- or 20-year-old, for that role. So they're reconceptualizing it as we speak."
So instead of a rugged Kevin McKidd or a larger than life Tyler Mane, are we getting a late-teens version of Thor, perhaps with McKidd playing his father, Odin?
We can only vehemently hope NOT.
I really think any assumption at this point would be jumping the gun. The script is no doubt still in flux at such an early stage and much can change between now and the start of shooting later this year or in early 2008.
