Over time, many of Barclay’s former assistants have gone on to great Hollywood success in their own right. One of his first assistants was Kevin Williamson, writer of "Scream" and "I Know What You Did Last Summer", and the creator and Executive Producer of the hit television shows "Dawson’s Creek", "The Vampire Diaries", and "The Following". Josh Barry, another former Barclay assistant, was the head of the television department at Prospect Park after working as an executive in Drama Development at ABC. He was recently tapped to be the President of Shawn Levy's 21 Laps Television as part of a major deal with Netflix. Sam Martin, the former HBO executive ("Bury My Heart at Wounded Knee", Lackwanna Blues) and film producer ("Pariah") and Jason Clodfelter, former VP of Drama Development, and now Co-President at Sony Television, both previously served as Barclay assistants.
