A cinema full of kids and parents waiting to watch Finding Dory were shocked when a trailer for an R-rated movie played beforehand.
The vice president of the theatre chain in the US was forced to apologise after the family friendly audience was exposed to the trailer for Seth Rogen's upcoming film, Sausage Party.

The animated film, which is rated R in the US, follows a sausage who tries to discover what really happens to products after they are purchased at the supermarket.
"Playing that trailer was a one-time honest mistake by a theatre manager moving screens around in effort to accommodate several large last minute groups wanting to see Dory," Walter Eichinger from the Brenden Theatre Corporation said to Bay Area News & Talk.
