Question: OK, I know ER has been on a long time, but I still want spoilers.

Answer: Exec producer David Zabel gave my colleague, Matt Webb Mitovich, the lowdown on John Stamos' two-episode arc this November. "You'll actually meet him in Episode 7," he says, "and then he's a major player in [Episode] 8, when a commuter plane crashes in a Chicago neighborhood." Stamos plays one of the paramedics on the scene, and Zabel likens the November sweeps episode to "a big action movie." The other central figures in the episode are Neela and Pratt.
