Brits bluff their way through film classics Casablanca, starring Humphrey Bogart and Ingrid Bergman, and winner of three Academy Awards including Best Picture (1944) - is re-released on Blu-Ray this year. A spokesman for leading movie publication Empire Magazine said: "The poll reveals the important place film plays in cultural credibility. Many feel they need to have seen the great films to be a credible member of society. Admitting to not seeing the likes of Casablanca or Citizen Kane might make us look stupid or a bit crass. What amazes us at Empire, is how skilfully some people have become in pretending to have seen these films. Wouldn't it just be easier to watch them? They are actually pretty good. The research found the biggest liars are eager to impress 16 to 24 year olds, with 50 per cent admitting to the deception. And Londoners are more likely than those in the provinces to say they've seen a classic film they haven't, with 35 per cent desperate to impress friends with their film knowledge.
