Parker, most recently seen on Broadway in Sharr White's The Snow Geese, will star opposite Peter Sarsgaard in "The Slap," based on the 2011 Australian short-run series of the same name and adapted by Other Desert Cities playwright Jon Robin Baitz.
The miniseries "The Slap," which is being produced by Universal Television and Australia's Matchbox Pictures (which produced the original), is adapted from the 2008 novel by Australian author Christos Tsiolkas and is described as a "complex family drama" that explodes when a man slaps another couple's misbehaving child.
Lisa Cholodenko is slated to direct the first two hours of the miniseries.
Parker will also join the second season of NBC's "The Blacklist." She will recur as a character named Naomi Highland. Executive producer-creator Jon Bokenkamp didn't reveal any more details, but he described Parker's character as "completely tied to Reddington [played by James Spader]."
