I watched this film over 20yrs ago on a NYE, hence me thinking of it now.
It was about an old movie theatre that was struggling with a local newer theatre.
They had the train go past the building to shake it whilst a western horse scene was on.
Also they turned the heating up on films with deserts on them.
It was an old film then so I think it was made between 1940-1970’s.
Sorry for the poor description but it was a long time ago. Any help appreciated.
Thanks
