Interesting, just been out for a drink with my cousin who lives in Durrington, Wiltshire. As we drove out of Durrington to the pub we passed a large field. "They've just been shooting the film 1917 up there, lots of the local teenagers got parts as extras, £150 a day. Unfortunately my son didn't go for it." His son has been moaning about lack of money in the summer break from college, if he'd got his finger out he might have done OK. He'd have made an excellent baby faced young tommy!
There's a movie from the late 60's or earluy 70's, "The Molly Maguires", that filmed a few sequences near my hometown*. One of my friends played a pusher in it....pushers being boys, usually around 10-15 or so, who sat on a crossboard and pushed coal down a chute with their feet.
*side note, three Mollies were hanged in the town courtyard, which by the time I was a teenager was the playground at the junior high school.
