Hell on Earth (Smash)

Karen sees the performance while trying to return the sunglasses she accidentally swapped with Ivy at the orange juice audition, and after yelling at each other, the pair end up drinking together and bonding.

Ellis (Jaime Cepero) chases Rebecca Duvall (Uma Thurman) for the production in the hopes that Eileen will make him co-producer.

After Derek (Jack Davenport) tells Eileen that he wants to take on other projects for a year while Tom and Julia finish writing the book for the show, Eileen searches for another director in the hopes that Derek will find out, and be scared back into committing to the show; her plan works perfectly.

[3] Two-time Tony award winner Norbert Leo Butz appeared as himself playing the lead role in Heaven on Earth.

The episode included a cover version of Rihanna's "Cheers (Drink to That)" performed by Megan Hilty and Katharine McPhee.
