The series, which was given a five-episode back order in November 2013 (bringing the first season of the NBC series to 18 episodes), struggled in ratings, most recently taking in a 0.7 rating in adults 18-49.
According to Deadline.com, 14 episodes have been shot, and 12 have aired. NBC had already scheduled a "SNL Sports Spectacular" special this week, and the network will look at the remaining two "Sean Saves The World" segments after the Winter Olympics.
"Sean Saves The World" features Hilty as Liz, Sean's long-time friend and co-worker who is a former therapist. She replaced Lindsay Sloane, who played the role in the pilot.
Hilty most recently played aspiring Broadway star Ivy Lynn on "Smash." Her stage credits include 9 to 5, Gentlemen Prefer Blondes and Wicked.
In addition to Hayes and Hilty, the cast of "Sean Saves The World" includes Linda Lavin (The Lyons, Collected Stories), Thomas Lennon (“Reno 911") and Echo Kellum (“Ben and Kate"). "Sean (Sean Hayes, 'Will & Grace') is a divorced gay dad who juggles a lot — his successful but demanding career, offbeat employees, pushy mom Lorna (Linda Lavin, 'Alice'), and weekends with his teenage daughter, Ellie (Sami Isler)," press notes state. "So when his 14-year-old bundle of joy moves in full-time, it's a whole new world. From keeping his boss happy, his employees motivated and enduring his mother's tactless 'advice' to raising a smart, grounded and healthy kid, it's going to be a growing experience, to say the least."
Hayes received a Tony Award nomination for his performance in the 2010 revival of Promises, Promises and hosted the 2010 Tony Awards. Hilty and Hayes previously worked together on "Smash," where Hayes guest-starred as a Hollywood actor making his Broadway debut.
