In the most surprising cast ever, murmur in the Bollywood by-lanes suggests that Katrina Kaif and Vidya Balan are all set to team up for an action comedy which will be backed by Aanand L Rai. The script is reportedly being penned and the two leads will decide their fate after a final narration. Interestingly, Aanand had also directed Katrina’s last film ‘Zero’, which was a box office debacle. However the filmmaker has once again approached Kat and is also keen on roping in Vidya as a parallel lead. Vidya is currently busy shooting for a biopic on math whiz Shankutala Devi. Katrina, on the other hand, will next be seen in Rohit Shetty’s cop drama ‘Sooryavanshi’, opposite Akshay Kumar.
