Shah Rukh Khan’s dwarf drama ‘Zero’ is scheduled to hit the theatres on December 21. Coming in a week later is Ranveer Singh’s ‘Simmba’. Despite the week-long gap between the two big films, a race to acquire maximum screens has already begun. Buzz suggests that SRK is planning to secure screens in the film’s second week to assure maximum eyeballs for ‘Zero’ while Karan Johar-produced cop drama ‘Simmba’ is also on the lookout for as many screens as possible. Rohit Shetty-directed ‘Simmba’ is vying for more than 3,000 screens across the country but may face some tough competition from ‘Zero’. Who will relent from the two best friends, Shah Rukh or Karan?
