First they began moving stuff in to change the houses.
Chimney stacks and aerials were added, then trees, plants, and fences for the gardens, and of course the Privet Drive road sign.
It was all very exciting.
Then the filming equipment came. I could see a big white screen to reflect light onto the actors, umbrellas for the rainy days, and rails for the cameras to roll along.
The director took over the lawn of the house opposite us.
It wasn't too much bother (apart from the fact that Dad had to park in Tesco's car park for the actual filming days), but they gave us a little cheque for the "inconvenience"!
