Is there a website that tells you what’s being filmed in your city, I’ve seen loads of catering vans and lorries and a large 2 story camper van type thing, they are all parked where filming crews normally park.
I’m going past on the bus so I’m unable to ask anyone.
To the best of my knowledge there's no specific website for answering questions like yours but local newspapers often report on filming activities in their areas.
You could join Next Door (used to be Streetlife) and ask there. Our local Council posts on there and warns of road closures/disruption when filming is occuring in the area.
