BURBANK (CBSLA) — “Star Wars” fans at a Burbank theater went to the Dark Side when a screening of “The Last Jedi” played without sound for 20 minutes.

Moviegoers were ready to stage a new rebellion when an AMC Theater in Burbank either could not or would not restart the 10 p.m. showing of the film.

An angry stream of fans, some in Jedi costume, stormed the lobby, screaming and yelling, over the lack of sound.

@AMCTheatres wow opening night showing of Star Wars at AMC Burbank starts without sound for 10min and staff refuses to restart the film! Unbelievably poor customer service! — Brock J. Stearn (@myanimator) December 15, 2017

Apparently there is an "uprising" at one of the Burbank movie theaters because, I guess, technical difficulties during Star Wars? What a world we live in. — kaitlin thomas (@thekaitling) December 15, 2017

Many ticketholders pointed out that they bought their tickets months in advance.

Burbank police were called to the theater at about 10:21 p.m. to disperse “an unruly crowd.”

The theater offered refunds or to move ticketholders to a non-IMAX screening, or to return Friday for another screening.
