I thought they were designed in 2011 or so but apparently not... In the film Dallas Buyers Club, set in the late 80's ,there's a poster of an orange Aventador on the office wall behind Matthew Mcconaughey's desk in his motel office... Oops.
Yes, I really want to punch the set dresser for that.
I don't mind the odd slight anachronism, I could have almost forgiven a Diablo but Christ, surely SOMEONE must have known that car was 25 years out of time?
