Amazon is proving that its serious about being an online TV network. A week after releasing the Fire TV set-top box and a few weeks after green lighting several new comedy and drama pilots for full production, the tech giant has announced today (Apr. 9) its third round of pilot shows, starting with two titles with A-list (or at least B+list) directors and actors. The first is a half-hour, young expatriate dramedy The Cosmopolitans by director Whit Stillman (of The Last Days of Disco and Barcelona).
