Filming for the popular television series "Longmire" began in late March 2015, notes International Business Times. Production plans had been unsure because of its cancellation by A&E in late August 2014. Warner Horizon began pitching it right away and quickly negotiated a deal with Netflix for season four.
Although no confirmed release date has been set by Netflix, season four is anticipated to begin sometime in the summer of 2015. A recent casting call for May 6 put out by Project Casting confirms they are still shooting. "Longmire" aired for three seasons with the A&E cable channel and was its most watched original drama series ever, reports Deadline Hollywood. Undeterred by the show's popularity, A&E insisted it wasn't profitable, citing desires by advertisers to reach ever-younger audiences. The cancellation of the show sparked one of the largest fan-supported reactions in its history for a cancelled show and fueled the quick pick-up by Netflix. The series is based on the Craig Johnson "Longmire" mystery novels about the stoic Wyoming sheriff, Walt Longmire, and his band of deputies, friends and criminally inclined townsfolk. Leading cast members Robert Taylor, who plays Longmire, and Katee Sackhoff as Victoria 'Vic' Moretti are confirmed for season four.
