SANTA MONICA, Calif.–Former Gov. Arnold Schwarzenegger is back in a starring role for the first time since he took office, as filming started today in Nevada and New Mexico for his new Western, “The Last Stand.”

The star plays a former Los Angeles Police Department officer who ends up sheriff of a small border town after a botched operation, according to Lionsgate. He must take on a drug kingpin who escapes the FBI and flees for Mexico, heading straight for the town.

Although he appeared in several small movie roles while he was governor, “The Last Stand” marks Schwarzenegger’s first top billing since 2003’s “Terminator 3: Rise of the Machines.”

He announced just weeks after leaving office in January that he would be reviving his movie career.

Korean director Kim Jee-Woon is helming the film, which also features Forest Whitaker, Johnny Knoxville and “Friday Night Lights”‘ Zach Gilford.

The script is by Andrew Knauer and Jeffrey Nachmanoff.
