Bad guys in films and TV always drove Mk 2 Jags cool guys drove E-types (think Austin Powers)
More common cars were Hillmans, Humbers, Austins (Cambridge and A40s) Vauxhalls (Victor, Viva, Cresta) Fords (Cortina Mk 1 and 2) Triumph Herald.
I'd choose the ones I wanted and make a shortlist then contact the owners' clubs to see if there were any enthusiasts with my ideal cars nearby and if they'd like to make a film. Should be quite easy with the internet.
