I noticed
Halloween was on the Freeview channel 4-7 - a Channel 4 offshoot, so had a look at it.
Wow! The difference between that and the Blu-ray i'm watching is astonishing. I watched the exact same sequence when Laurie and her two friends are walking down the street. As i initially watched it i thought to myself "This was definitely not filmed in October. The trees are all full green leafed and it looks like brown leaves have been scattered on the road to try and make it appear to be 'Fall'"
When i looked at the version on 4-7 i couldn't even see the brown leaves on the road.
