It was a live, televised remake of the 1978 film Grease, executive produced by Marc Platt, directed by Thomas Kail, and starring Aaron Tveit, Julianne Hough, Carlos PenaVega, Vanessa Hudgens and Jordan Fisher.

[4] On July 9, it was announced that Aaron Tveit would star as Danny Zuko in the live TV broadcast, and Carlos PenaVega would play the role of Kenickie.

[9] Kail explained that "very early on as I started imagining what this could be, talking to Marc Platt, our executive producer, and the folks at Paramount, one of the things we really were very focused on was trying to capture the spirit of both the original companies of Grease and that film that has left such an indelible impression on all of us.

"[10] The production also contained several new songs including the original, "All I Need Is an Angel", which was written for the character of Frenchy (Carly Rae Jepsen) by Tom Kitt and Brian Yorkey of Next to Normal fame.

[12][13] In order to be appropriate for broadcast television and to appease advertisers, several songs were edited for content; Platt stated that his goal was to make Grease Live a "family-friendly" show, but still wanted to maintain "the appropriate edge" the musical required.

[14] The use of outdoor sets for portions of the production led to concerns that it could be affected by weather, especially in the wake of forecasts calling for a 100% chance of precipitation and possible thunderstorms on the day of the telecast.

[15][16][17] While prepared for the possibility of rain, wind was also a major factor: at around 3:00 p.m. PT, an hour before the telecast went live, Platt was informed that a particular structure on the outdoor set could not be used for safety reasons.

By 3:40 p.m. PT, while the team was in the process of re-staging the opening number to exclude the structure, the rain and wind passed, and engineers cleared the use of the structure—allowing a return to the original staging.

"[19] On the day of the broadcast, Vanessa Hudgens announced on Twitter that her father, Greg, had died of cancer the night before, and that she would dedicate her performance in Grease Live to his memory.

[20][21] Platt told Entertainment Weekly that he was "fiercely proud" of Hudgens' handling of the situation, describing her as a "very determined young woman" who "knows that the show has to go on, as any actor of the theater or in a live event knows.

"[15] Additionally, Fox and Paramount allowed the production to be dedicated in memory of Greg; Platt went on to say that "the cast was behind her and we all joined hands and said, 'We're going to live in this moment.

[40] Megan Vick of TV Guide felt that Kail had "upped the standard" for live television musicals, and had "successfully managed to combine all the nostalgic elements of Grease that everyone expected while creating a new experience.

While praising "All I Need Is an Angel" for demonstrating Carly Rae Jepsen's capabilities as a singer, Vick felt that the song was too modern for a musical that is set in the 1950s.

[41] Jeremy Gerald of Deadline Hollywood noted that Grease Live was broadcast "with nary a hitch and one last-minute change in the out-of-doors opening number that paid tribute to the greatest movie musical of all time, Singin' in the Rain".

Vanessa Hudgens was judged to have "stolen" the show, and that Aaron Tveit and Julianne Hough "couldn't be better matched as the head of the T Birds and the sweet new girl from Utah."

"[18] Variety's Maureen Ryan felt that the performance of Hough and Tveit was weak, explaining that "when Danny has all the presence of a glass of milk and even the black-clad Sandy of the final scenes exudes all the sexual danger of a church choir director, well, rest assured that those concerned about the Grease legacies of Travolta and Olivia Newton-John have nothing to worry about."

She concluded that "If Fox can get the lead casting right in future and snag Kail again, audiences will surely be hopelessly devoted to the network's next live endeavor.

A Broadway musical that originally spoofed our rose-tinted-glasses view of the '50s has turned into a nostalgic wallow, leaving the show with an odd mix of tones – and in this particular version, a book that sometimes seemed to get lost between songs and inside jokes.
