Sure, it was the Vikings

I read this in the latest issue of Premiere magazine, in a blurb about the (crummy) upcoming movie Pathfinder:

(Karl Urban, lead): "For the longest time, everyone's gone with the notion that Columbus effectively discovered America, and they forget about the Vikings, who were there [centuries] before."

Followed later by:

"In this way, [his Viking character] Ghost is kind of like the first American."

"Kind of," indeed. The story, according to Premiere, concerns a Norse baby reared by Native Americans... who would then be zeroth Americans, I suppose?
