John Ridley (12 Years a Slave) is a screenwriter that executes each stroke of the pen with meticulous research backing every bit of each scene. The proof is in the pudding: adapting a screenplay? Writing an original based on true events or real people? Research the topic until there is nothing left to find. 90% of that information won’t be used in the final product, but it will be needed during the editing phase.
