ER has been in NBC's Thursdays-at-10 time slot for so long (going on 15 years now!) that it's hard to imagine what could replace it when the show goes off the air next Spring. But now there's news of one possibility — and it comes from a familiar source: ER's own executive producer, John Wells.
Wells will be producing a pilot for NBC called LAPD, which is already being considered as a potential replacement for ER on Thursday nights.
