As Bullet served as co-production for a Mumbai production house, the diversity of talents are challenging, but fun. The very most challenging part were the cute casts, yet semi - controllable. They could open books, used the remote control, interacted with talents and all, though multi - takes weren't an ideal practice. Nevertheless, the full team support; chimp trainers and directors managed to project this commercial out amazingly. Thanks to the mischievous chimps for the cooperative acts.
