The Tuesday preem of Sony’s “Battle: Los Angeles” missed its platoon leader, helmer Jonathan Liebes-man, who was stuck in London on the set of “Wrath of the Titans.” Even so, the opening went off like a high-wattage flair over Westwood’s Regency Village Theater.

Producer Neal Moritz sent the absent director a choreographed “Congrats!” from the packed crowd on Moritz’s flip phone.

At Sony’s tented afterparty, “Battle” stars Michelle Rodriguez and Cory Hardrict kept company with Marine officers. Rodriguez, who took a turn as one of the night’s DJs, described herself as more the Marine type.

“Even though I play an Air Force tech sergeant (in the film), the real training came with the Marines,” Rodriguez said. “And I kind of look like a Marine. To me, that’s second nature.”

Moritz described the alien-invasion pic. “What if they invaded our shores? Who would be there to protect us and what would go down? Because honestly, I love those heroes,” he added, praising America’s soldiers.
