From falling into a ditch to getting hit by an auto -- Bollywood actress Deepika Padukone faced it all while shooting for her upcoming movie Lafangey Parindey and she feels that it has been the most challenging film of her life. "This has physically been the most challenging film for me. I had to learn how to skate, then I had to act blind, I had to hold a pigeon, run behind a chicken, get bitten by a dead fish - don't ask me how," Deepika said.
