The actor wanted to portray his role perfectly so he decided to get a new hairstyle for the look. Most of the US prisoners sport cornrows hairstyle, which is a series of thin braided hair running down the scalp. This hairstyle is very easy to maintain so it is a huge hit among the jail inmates.
Edward told the reporters, “First off the cornrows were real. But there weren"t any hairstylists in Hollywood who could do cornrows properly, so we found a lady called Crystal from Detroit who does a nice clean set of rows."
The 41-year old actor said that he really enjoyed researching for his role because it gave him time to find out the inner workings of the mind of convicts. He said “Just the couple of weeks I got to sit around in this prison and talk to these guys who are imprisoned, it was a revelation for me, and it was a hugely memorable experience. I love that part every time."
