"Pilot" was written by series creator Emily Spivey and was directed by James Griffiths. The series was based on creator Spivey's life when she went back to working on Saturday Night Live after giving birth to a baby boy.^[1] Due to the nature of her job, she was required to take care of the baby and work late nights.^[1] She decided she wanted to make a show based on those extremes.^[1] On February 1, 2011, Up all Night received a pilot order.^[2] Applegate was the first cast member signed on to the series.^[3] She is credited as a producer for the series.^[4] Rudolph was the second main cast member to sign on to the series.^[5] Rudolph had previously worked with the series creator on SNL and Spivey had wanted to work with Rudolph before the series plot was established.^[1] Arnett was the third main cast member to sign on to the series.^[6] The series was officially picked up for 13 episodes on May 15, 2011.^[7] After the success of Maya Rudolph's movie Bridesmaids, Up All Night went through some retooling which now has her character Ava, as a talk-show host, and Reagan now as the show's producer, instead of them being PR executives.^[8] This led to Rudolph's character being compared to Rudolph's impression of Oprah on Saturday Night Live.^[9]

Club reviewer Erik Adams called the episode "one of the funniest pilots of the new fall season" commenting that "Showrunner Emily Spivey does well not to mine the saccharine elements of parenthood. She makes Up All Night’s intentions apparent from the moment that Arnett and Applegate can’t bring themselves to quit cursing in front of lil’ Amy."^[12] Another A.V. Club reviewer Emily VanDerWerff was slightly more negative towards the pilot writing that "The pilot for Up All Night isn’t very funny, especially given the people working on it, but it’s often well-observed.".^[12] Her main criticism was that the series was "essentially, two shows in one" calling the workplace scenes "like a copy of many other shows on the air".^[12] The two reviewers eventually gave the series a B.^[12] HitFix reviewer Daniel Feinberg gave the series pilot a positive review, but disliked the office settings and the writing for Rudolph's character commenting that "Will Arnett and Christina Applegate are playing parents, but Maya Rudolph is playing a sitcom character".^[13] He ultimately gave the series a B− rating the Baby Scenes with a B+ and the Rudolph scenes a C/C−.^[13]
