Posted by Deadline‘s Mike Fleming: “I had done a long interview with Green Book‘s Mahershala Ali and Viggo Mortensen, where those actors kept saying they found the handle on their characters by listening to a series of audio tapes featuring the actual voices of Dr. Donald Shirley and Tony “Lip” Vallelonga.

“I thought tracking down and publishing them might help swing the narrative of Green Book back to the road trip as they sat in that car together and were the only ones who witnessed the events and the institutional racism and hatred they encountered in the Jim Crow South. I got my hands on these tapes and, with the help of an editor, put them in the digestible soundbites you can hear below.

“It takes a while to get through them, but you might want to do it soon. I got them on the sly, and have no idea if I’ll be told to take these down.”

In other words, listen to these tapes ASAP.
