This is not the Katie Holmes we're used to.

The 36-year-old actress is making her directorial debut in All We Had, the upcoming film in which she also stars, and a new set photo reveals a gun-wielding, wild-eyed Katie like we've never seen before.

Nor is this Katie's first major style shift on set of the film. Earlier in August, the former Dawson's Creek star was photographed wearing a tiny, skin-baring denim minidress.

A source told ET earlier this month, that Katie had not had visitors on set yet, including Suri, her 9-year-old daughter with ex-husband Tom Cruise.

ET also learned from a source that Katie increased security while shooting the movie to try and keep paparazzi away from production.

Meanwhile, in May, Jamie Foxx shut down rumors that he and Katie were dating, after a photo surfaced of the two holding hands.

"I guess some knuckle head person who was here hit us with the phone cam," Jamie told ET, explaining that he and Katie we're just friends. "I guess they are trying to get money for whatever. It's amazing what people will do to sell you out."
