The Los Angeles Film Festival has set a world premiere of Relativity’s “Earth to Echo” for June 14 — three weeks before the July 2 opening of the sci-fi adventure.

“Earth to Echo” stars Teo Halm, Brian “Astro” Bradley and Reese Hartwig as friends whose neighborhood is being destroyed by a construction project who find a cryptic signal has infected their phones.

The festival, headquartered at the Regal Theater, will also offer a pair of family events on June 14 — a “Gravity Falls” Live presentation, based on Disney animated show with Jason Ritter and Kristen Schaal, and a Future Filmmakers Showcase of short films made by high-school students.

The festival had announced previously that Bong Joon-ho’s “Snowpiercer” will be the opening night film on June 11 while Clint Eastwood’s “Jersey Boys” will close the festival on June 19.

The festival has also released a promotional trailer touting the Los Angeles creative community with Billy Bob Thornton reading Shel Silverstein’s poem “Invitation.”
