Coma (9 PM, A&E):
Ridley Scott and the late, much-missed Tony Scott are behind this two-night miniseries from the writer of Black Swan:

A&E Network presents "Coma," a four-hour epic two-night event from Ridley and Tony Scott featuring a multiple Academy Award and Emmy Award-winning cast with Lauren Ambrose ("Six Feet Under"), Steven Pasquale ("Rescue Me"), Geena Davis, James Woods, Ellen Burstyn and Richard Dreyfuss. "Coma," a modern day retelling of the bestselling novel by Robin Cook and based on the film by Michael Crichton, premieres on Labor Day, Monday, September 3 and concludes on Tuesday, September 4, airing at 9PM ET/PT on both nights. "Coma" also stars James Rebhorn ("Law & Order," "White Collar"), Joe Morton ("The Good Wife"), Michael Weston ("House") and Joseph Mazello ("The Pacific," "The Social Network"). Emmy Award winner Mikael Salomon ("Band of Brothers") directs the John J. McLaughlin (Black Swan) penned script. From the team behind A&E's Emmy-nominated miniseries "The Andromeda Strain," and the hit drama series "The Good Wife," "Coma" is a thriller about a young doctor (Lauren Ambrose) who discovers that something sinister is going on in her hospital after routine procedures send more than a few seemingly healthy patients into comas on the operating table.

This was always going to be an interesting experiment, but now it's one of our last chances to see something new with Tony Scott's name on it, and remember how much great entertainment he brought us.
