Actress Shagufta Ali, who worked with Govinda in 'Hero No. 1', said that he is a bigger perfectionist than Aamir Khan. "He does 25 rehearsals," she said. "David (Dhawan, director) sir would okay the take, but he'd still insist and...apologise to others. His eye for perfection was so strong that he didn’t care if...person opposite him was tired," she added.
