It's the future!
No it isn't, but that doesn't mean this isn't lovely film showing the Butlins monorail being built and operated.
I like the clean-coated and quiffed workers laying down the fibreglass. Surely the place wasn't that spotless? The lack of face masks during fibreglassing and spray painting is worrying.
Never mind, the colourful film looks great in that very 1960s way colour films did. The sun always shines at Butlins!
