Gurney discusses his recent turn into political playwriting ("O Jerusalem", "Mrs. Farnsworth", "Screen Play"), how he developed his career while keeping a "day job" for more than 20 years -- teaching humanities to aspiring engineers and scientists at M.I.T., and why one of America's most popular playwrights has taken to premiering his new plays in a tiny theatre Off-Off-Broadway.
