marichupoya Roynte sisterde 4 hr interview 24 news program kandapol I thought it would've made a fantastic film however in the perspective of her as she was the only family member in Kerala who tried to solve the case herself. I thought it would be to have two stories of the police investigation and perspective of roy's brother and sister in play..

I would've casted the film like this:

Joju George or Indrajith as Kozhikode SI Kg Simon or whoever the main investigative officer was
Parvathy or Lena as Roy's sister Renege
Kunchacko Boban as Roy's brother Rojo (Extended Cameo lives in the states)
Maala Parvathi as Jolly
Mukesh as Roy
Suresh Krishna as Shaju (jolly's current husband)

Director - Aashiq Abu (Virus pole international level edakkan pattunna sambhavam aanu)
Rajeev Ravi
Amal Neerad

This is a high profile serial killer case which could be made into a series or international level film with a top notch director without any Superstar actors in my opinion they could make something very quality driven without a lot mainstream actors but it doesn't need mammookka or lalettan in my opinion
