The Teaser Trailer Ambush, the anticipated directorial debut from John Salvitti (In the Line of Duty 4) has finally arrived in all its gritty glory. And when we say gritty, we mean it. We’re talkin’ Henry: Portrait of a Serial Killer gritty.

Ambush marks Salvitti’s entry into writing, directing and editing his original brand material. “It’s sort of in the vein of Fight Club with the PTSD/split personality. The story centers on issues we see everyday in today’s media. A constant barrage of violence, shootings, bullying and political tensions – issues that are so burdensome, hey’re driving some to engage in violence. That’s Ambush,” says Salvitti.

Salvitti is a martial artist known for his roles in Hong Kong films like Crystal Hunt, Cheetah on Fire, In the Line of Duty 4 and Flash Point – as well his action choreography work in Special ID, Kung Fu Killer and Pound of Flesh. Despite for being known for his fight choreography (and his close association with Donnie Yen and Yuen Woo-ping), Salvitti says that Ambush will deliver more on “phycological action and gun violence” than on martial arts.

Here’s what you can expect from the plot of Ambush: Kal is a visitor to Los Angeles suffering with PTSD and on the verge of carrying out a lone wolf attack. But first, he must rescue his girlfriend from her assailants. Question is: Who lives, who dies and who was merely a fragment of one’s imagination?

The film stars New York theatrical actor Maxx Black in the lead role, with Vietnamese theatrical actress Sai thien Le, and from Milan Italy Model, Sabrina Bertaccini.

Ambush is currently in final stages of post-production.
