Exclusive: Max Martini has signed on to star in the Guillermo del Toro-directed “Pacific Rim” from Legendary Pictures.

Charlie Hunnan, Idris Elba and Charlie Day are already set to star in the sci-fi pic, with Travis Beacham tapped to pen the script.

Pic tracks an alien invasion that threatens Earth, and the people who come together to defend it.

Martini would play part of the resistance that fights the alien invasion.

Legendary’s Thomas Tull will produce along with Jon Jashni.

Production is expected to get underway this fall. Legendary had no comment.

Martini is currently gearing up to direct a script he penned called “Will Gardner,” starring Jeffrey Dean Morgan.

He is repped by ICM and Forward Entertainment.
