Dont get smart; I know you know the MI6 HQ is the real one on Vauxhall Road (oops, I do hope the SAS dont kill me). But remember that showpiece tank/car chase through St. Petersburg? Well, surprising as it may seem, Eon Productions couldnt just trash Russias capital in the name of 007 spectacle (it would have made the Cold War a lot easier if they could). So, with little more than a few Cyrillic plaques, production designer Peter Lamont constructed an elaborate square around the back of Leavesden Studios. And Trevelyans wonderfully grim Soviet trainthe one that looks like an evil Thomas the Tank Enginewas actually traversing Peterboroughs Nene Valley railyard. Now, this is a fascinating placetrains from around the world are stored there, and so with minimal fuss, your showpiece train chase can be affordably filmed in Cambridgeshire! It can also be seendoubling as East Germanyin Octopussy (1983).
Giveaway British Character Actor: Okay, that would be cheating on this one.
