Chris Hemsworth: Oakley Party with Liam!

Chris Hemsworth and younger brother Liam hit the Oakley Snowball Run Party on Main Street during the 2011 Sundance Film Festival on Friday (January 21) in Park City, Utah.

The bash, which Oakley hosted with 901 Silver Tequila, was held on Main Street and featured a performance by hip-hop and rock band Free Sol.

Last week, the two celebrated Liam‘s 21st birthday with a bash at Cleo and The Colony in Los Angeles.

The brothers then attended a Golden Globes after party together.

At the Globes, Chris, 27, talked a bit about Thor and his other upcoming action movie The Avengers.

“I just read the script [for The Avengers], an early draft, and it’s mind blowing,” he said. “I have no idea how they’re going to shoot it. It’s huge and incredible.”
