Fox execs Terence Carter and Carolyn Cassidy, Bones EP Jonathan Collier, The League’s Jeff Schaffer and Dan O’Keefe, and Fox Writers Studio co-head Nicky Weinstock are among the mentors of Harvardwood’s third annual “Most Staffable TV Writers” program this spring. The Harvard University-sanctioned nonprofit each year selects five writers based on original TV pilot submissions and sets up each winner with a one-on-one mentorship with a pair of TV pros. The 2013 honorees are Sam Chalsen, Forensic State (one-hour drama); Sue Chung, Shrouded (one-hour drama); Allison Kiessling, Elixir (one-hour drama); Matt Roller, Homeschooled (half-hour comedy); and Ryan Slattery, Market & Castro (half-hour comedy). In its previous two years, writers selected by the program went on to score agency representation at CAA, ICM, Circle of Confusion, Management 360 and Echo Lake. Members of the Harvardwood Writers Program have nabbed gigs on FX’s Justified, HBO’s The Newsroom, Fox’s Family Guy, NBC’s Awake, USA’s Covert Affairs and TNT’s Perception. The organization is open to Harvard alumni, students, faculty, and staff as well as non-Harvard-affiliated figures in the arts, media and entertainment.
