I wonder if the film showing was Champion the wonder horse?
Farm horse gatecrashes into cinema
Stunned film-goers were shocked when a horse jumped the queue and burst into a local cinema, a source has said.
The horse was one of three which escaped from a farm and ran through the automatic doors at the Cineworld complex in Boldon, South Tyneside.
It cantered down a corridor before turning round and fleeing through the exit as couples, friends and families looked on.
