Stars are known to aggressively promote their films, but few can match Abhishek Bachchan's enthusiasm, as he attempts to enter the Guinness Book of World Records by making maximum public appearances in at least six cities in a span of 12 hours to promote his latest film “Delhi 6”. Starting on Friday morning when “Delhi 6” releases, Abhishek will travel to as many events in as many cities as possible within 12 hours. Speaking from Dubai Wednesday where he was attending the film's premiere, Abhishek excitedly said: “It's an idea that has been with me for a while ever since I heard about some German actors who set a world record by attending five public events in twelve hours. I want to beat their record. I'd do at least 6-7 appearances in 12 hours in six cities. It could go up to seven cities.”
