Posts about Chris Hemsworth
In the comics, Thor and Odin are titles held by whoever holds the Thorforce and Odinforce respectively, each of which are Skyfather powers. With Odin dead and Chris Hemsworth having a definite best-before date looming (it becoming harder and harder to disguise his aging, something the immortal god of thunder isn't supposed to do), they're going to need a way to keep him around but explain his older appearance.
It would make perfect sense to have the current Thor ascend to the role of Odin, something he does in the comics. This would not only allow a young newcomer to move into the role of Thor, but also provide a recruit for the Young Avengers in Phase 6 or Phase 7. And it would justify an older and more mature look for Hemsworth.
