Jackson Rathbone exuded quiet confidence whenever he stepped foot onscreen. The television and film star rose out of relative obscurity with a breakout role in "Twilight" (2008), one of the most successful film franchises of all time. Rathbone played Jasper Hale, a "newborn" vampire who needed to control his urge to feast on human blood, especially that of the saga's protagonist Bella Swan (Kristen Stewart). The film series, like the Stephenie Meyer novels they were based on, followed his character's personal journey, from coping with his killer instincts in "Twilight" and "The Twilight Saga: New Moon" (2009), to becoming the unsung hero of 2010's "The Twilight Saga: Eclipse." That same year, Rathbone played a warrior in M. Night Shyamalan's "The Last Airbender," a physically challenging and emotional role that kicked the talented actor's career into high gear.
