Audiences filled with “Finding Dory” fans, including small children of course, got more than they bargained for when the wrong film began to play in a theatre in California.

The family-friendly fish film accidentally had Seth Rogen’s R-rated animated comedy “Sausage Party” trailer play to the shocked crowd.

Many of the movie-goers complained about the incident which led to an apology from the vice president of the theatre.

“Sausage Party” is about one sausage’s quest to discover the truth about his existence and has a star studded cast voicing the picture.

Stars like Seth Rogen, Kristen Wiig, Jonah Hill, Bill Hader, Salma Hayek and Michael Cera all have major voicing roles in the movie.

The trailer in question portrayed a violent scene of human-like food items meeting their end in seemingly normal ways, such as a potato screaming in pain as he is skinned alive and a woman eating squealing baby carrots.

“Finding Dory” is now playing and “Sausage Party” will be in theatres August 12.
