As buzz continues to grow for “Warrior,” Frank Grillo — who plays Joel Edgerton’s trainer in the September release from Lionsgate — is setting up his next pair of pics.

Grillo is set to play a gangster in WB’s ensemble crime epic “The Gangster Squad” and a key supporting role in the indie cop drama “End of Watch,” starring Jake Gyllenhaal and Michael Pena.

“The Gangster Squad” already stars Sean Penn, Ryan Gosling, Josh Brolin and Emma Stone, with Will Beal penning the script and Ruben Fleischer directing. Film is based on the Los Angeles Times’ seven-part series “Tales From the Gangster Squad,” which chronicled the LAPD’s efforts to keep East Coast mobsters out of Los Angeles in the 1940s.

Grillo will play Ragan, a Chicago gangster who operates the Continental Wire Service.

“End of Watch” follows the longtime partnership of two LAPD officers, played by Gyllenhaal and Pena. Grillo would play tough commanding officer to whom they answer. Pic will be written and directed by David Ayer with Anna Kendrick, Natalie Martinez and America Ferrera also starring.

Grillo can be seen next in “Warrior,” which has already received positive response from early screenings, including at last week’s Comic-Con. He also recently finished production on “Lay the Favorite,” starring Rebecca Hall and Bruce Willis, as well as “The Grey,” directed by Joe Carnahan.

Grillo is repped by CAA and Management 360.
