XJ6 first launched Sept 68 so either (1) film is 69 onwards or (2) if a mid 60s film any Jag is earlier model. Apart from possibly the wheels (which might be 60+ Jag Mk2, 66+ 420 or 62+ E-Type, or might not) nothing obvious which looks Jag-like. Steering wheel looks old but not very Jag. Body is a bit like very early 60s Marcos on steroids - eg http://www.marcosjem.co.uk/history.html - but that's only a passing comment and not an identification. Any other photos?
