The darkness continues in Taco Bell's new Nacho Fries thriller

Taco Bell's Nacho Fries are back, and so is the conspiracy-theory movie-themed marketing push for the limited-time side.

Nacho Fries were a big hit for Taco Bell during their January-March run, so much so that they're back at the Yum Brands chain on July 12.

In the first ad, Josh Duhamel starred as a man trying to uncover why the fast-food chain doesn't sell fries, in response to a dinner table request from his daughter. Darkness ensued, complete with "The Burger People" conspiracy theories and creepy clowns.

In the new "Web of Fries II: Franchise Wars," it's the daughter, grown up enough to star in the role of "woman seeking revenge in a mystery," who is looking into the matter. Duhamel reprises his role, despite his end seeming imminent in the first part of the campaign, when his car crashed into water.

The chain is playing up the movie-themed marketing with a big tie-in to "Demolition Man," recreating that movie's version of one of its restaurants at this month's San Diego Comic-Con. (Remember, as the movie proclaimed: in the future, "all restaurants are Taco Bell").
