Toilet Ek Prem Katha most probably will shift to viacom18 as they have produced it, much like what i had stated about simran and recently it had shifted to Viacom18. Drishyam, Bhaag Milkha Bhaag might also shift to viacom18, only if viacom18 and star/disney decide to continue agreement then these films might stay on with star/disney.... Similarly if Drishyam rights r with Ajay Sir and his agreement continues with star/disney then it will also remain with star/disney. Incase Rangoon satellite rights r with NG Grandson then it will shift either to star/disney or zee but highly unlikely as if this would have been the case then premiere would have happened on star gold but still producer can acquire rights later on too
