In West is West, the 2010 sequel to Ayub Khan Din's East is East, the opening shot is a long-shot of a Northern British town's alleyway (don't think it can be considered a gennel?):
Is there any more information on where exactly this particular shot takes place? If not, is at least the rough location of it known?
Probably the back of Silverdale Street, Manchester - now demolished & a new estate built.
Google streets view of it in 2012 - open space, but this is probably within a few yards of it, the cobbles are all that remain, if you look away from the road, across the grass, to East or West

That type of terraced housing would very frequently back onto such small back streets - it's all very Coronation Street ;)
btw, this wouldn't qualify as a ginnel, it's simply a 'back street'. A ginnel would be smaller, usually just wide enough for one or two people walking.
Late edit
Using Google's street view history, I've found the chippy, corner of Silverdale & Toxteth
The shot may be directly behind the chippy, but Google didn't capture a good shot of it from either end. This is the closest we'll probably ever get.
This is it today…
