They were expecting to see Finding Dory, but instead saw the horrific trailer for a Rated-R animated film.

The mistake led to the viewing of the “Sausage Party” trailer for the PG crowd in mid-June at Brenden Theatre in Concord.

“Sausage Party” is a movie about one sausage leading a group of supermarket products on a quest to discover the truth about their existence and what really happens when they become chosen to leave the grocery store.

“Playing that trailer was a one-time honest mistake by a theater manager moving screens around in effort to accommodate several large last minute groups wanting to see Dory, the wrong movie was started by mistake,” said Walter Eichinger, Vice-President of Operations for Brenden Theatre Corporation.

“Our movies are now started and stopped by computer and a click of a mouse. We moved a couple of screens to larger houses to accommodate some walk-up groups over a very, very busy Dory weekend. In the rush one hardworking manager clicked the wrong movie. It was caught soon but not until that trailer was played. We regret it, apologize for it and we are not happy that it happened. We fully realize that this trailer is not appropriate for Dory and we would never schedule something like that,” according to Eichinger.

“The trailer for Sausage Party is not and has never been scheduled with Dory,” Eichinger added.
