Joker - promo shoot for The Dark Knight

Hi! I'm a final an film student and the Joker role has always been a favourite of mine and I am carrying out some research to see who people think is their favourite live action performance of the role in a film and whether ou not it is linked to memory. It would be a great help if anyone could fill out my questionnaire, it should take no longer than a few minutes.

No personal information such as name ou contact details are needed as it will be kept anonymous.

Thank you!
