Sonu Sood, who will be playing the antagonist in Simmba, says grey characters always interest him as there is more scope of performance.
The 44-year-old actor has already started his preparation for the Rohit Shetty-directed cop drama, starring Ranveer Singh in the lead.
“It is very challenging (role). When grey character gets entertaining, the job is done. We are all here to entertain you and I am sure you will be entertained,” the actor said.
