NBC has given a 10-episode straight-to-series order for “Emerald City,” a reimagining of the classic Frank L. Baum books that have inspired everything from “The Wizard Of Oz” to “Wicked.” NBC is also ordering eight episodes of the miniseries “The Slap,” based on the critically-acclaimed Australian project of the same name that aired in 2011. Written by Jon Robin Baitz (“The West Wing,” “Brothers & Sisters”) and also produced by Universal Television, “The Slap” is a complex family drama that explodes from one small incident where a man slaps another couple’s misbehaving child.
