Liam Hemsworth angered by reporter?

Liam Hemsworth became visibly annoyed by a reporter thinking he mistook the actor for his older brother Chris Hemsworth.
As Liam, 25, walked along the red carpet at Comic-Con in San Diego, the reporter said: "Hi I'm Chris, it's nice to meet you."
But Liam replied, "You called me Chris? It's Liam. You called me Chris didn't you?" The reporter was quick to defend himself, saying: "Oh no, I said I'm Chris."
At which point Liam backed down, reported Female First. "Oh, you're Chris. Phew. OK, you're Chris. I'm Liam. We're good," he said.
