Not for nothing do they call him the Mountain. At more than 400 solid pounds, "Game of Thrones" television star Thor Bjornsson will be at U.S. Bank Stadium on Sunday.

If the native Icelander can't get the crowd to rock the building with the Skol chant before the game against the Green Bay Packers, well, who can?

The 6-foot-9 Bjornsson will step out onto a platform above the western end zone to sound the gjallarhorn.

Then he will raise his massive, tattooed arms to clap above his head to lead an anticipated full house of 66,200 in the Skol chant.

In Iceland, it's called the Viking war chant.

A video of 10,000 Icelanders bellowing the chant and clapping in sync went viral after the hometown team's underdog Euro Cup soccer tournament in the summer of 2016.

USA Today called it the "coolest chant in all of sports" and "bone-chilling."

With an unofficial handoff from Iceland last year, the Vikings appropriated the chant for the inaugural season at U.S. Bank Stadium in 2016.

They've been using it at every home game.

The consensus has been that fans are still trying to get the hang of it and have yet to fulfill their potential that could propel the chant to the heights of sports traditions.

Maybe Bjornsson's commanding presence will get the Vikings' fans going on Sunday.

Maybe there will be enough fans of HBO's hit "Game of Thrones" among them to spark that enthusiasm..

Hafpor Julius "Thor" Bjornsson is an Icelandic strongman and actor.

He participated in the chant on video at a Vikings game last season. On Sunday, he'll be in the big house.
