Think you already know what Kellan Lutz was doing before being cast in the highly-anticipated vampire film 'Twilight?'

Many fans will recognize Lutz, who plays Emmet Cullen in 'Twilight,' as character George Evans on this season's "90210," the spin-off of the popular '90s teen drama.

The 23-year-old actor has also been busy playing an army soldier in the HBO miniseries "Generation Kill," which is based on the experiences of a Rolling Stone reporter embedded with troops in Iraq. His latest film, 'Deep Winter,' is the story of best friends who set out to be the first to ski a dangerous Alaskan peak.

Lutz is real-life friends with 'Twilight' co-stars Robert Pattinson, Nikki Reed, Ashley Greene, Jackson Rathbone and Taylor Lautner.
