Actress Parineeti Chopra, who'll portray badminton player Saina Nehwal in her biopic, has shifted to Ramsheth Thakur International Sports Complex in Mumbai to prepare for the film. "I'd have wasted at least 4-5 hours in the to and fro from my house to the location," Parineeti said. "I want to perfect myself before shooting...portions where I've to play...Saina," she added.
