Actress Deepika Padukone is reportedly planning to quit the second installment of her science-fiction 'Kalki 2989 AD'. The decision is reportedly due to her demand of having an 8-hour work shift. Due to the film's massive scale, the makers are reportedly finding it difficult to accommodate her demand. Earlier, Deepika reportedly quit Sandeep Reddy Vanga's 'Spirit' over the similar issue.
