SUperman II/Superman IV - Hertfordshire/Surrey as East Houston and Milton Keynes as Metropolis…
Watching recently Whoops Apocalypse, which brilliant/terribly recreates USA and France in various LWT-region locales, and in the studio.
That Mars cycling ad is clearly filmed in South Africa. The city looks very un-English. You can tell when most ads are set in a strange Mid-Atlantic suburbia. That’s SA.
80s Irwin Allen miniseries the Memory of Eva Ryker uses the Queen Mary at Long Beach to simulate Southampton (motorcyclists Ernie VIgil and NIck “the revolution” Brocha did too Queen Marysploitation short the Stowaways) and like the Thorn Birds, features a very Californian, very rocky, mountaineous Outback - which should be flat as a pancake, and has a terrible Afrikaner-Cockney accent from John ALderson (Wyatt Earp in Doctorr Who and the Gunfighters)
GReen Street 2 - set in a desert prison supposedly in England, with a few Aussie and English actors, eg Martina SIrtis, Treva Etienne, and Aussie Vernon “Wez from MadMax II” Wells.
Killer Elite with Jason Statham has a scene set in the Thames with a sign warning of sharks. It was filmed down under.
Various things have shot in Vancouver - not just doubling for US but UK - that JK Rowling biopic, Stonehenge Apocalypse, movie the MIracle of the Cards which badly uses Gastown as London, though the Magician’s HOuse - a Welsh-Canadian coproduction actually did its best to turn BC into Wales. Some films can be less obviously filmed places, thus convincingly. For example, recently UK-Canadian coproductions have returned, eg Hector and the Search for Happiness, London exteriors yes, but a lot of less obvious Vancouver exterior/studio interiors doubling as UK, and also the partly BC-shot Imaginarium of Dr. Parnassus.
NIghtmares and Dreamscapes - Crouch End - a Ramsay Street Melbourne suburb badly plays London - complete with ozpost vans and Cockaussie kids.
And the good old Universal backlot has been used as Ireland (Heroes’ Cork, Star Trek Voyager’s Fair Haven, the 80s Twilight Zone’s Killany (sic), Belfast in JAG), Wales (the Wolf Man), London in everything from Basil Rathbone’s Holmes to Columbo to that recent EE Kevin Bacon ad and East Germany in every 80s action series…
