Production

Development and writing

At the

Todd Helbing said the episode will act as a sort of midseason finale and be "a little bit different,"[3] with "a big twist to carry us over".[2]

Ahead of the premiere of the fifth season, Helbing explained that "[they] wanted to do something special" for the episode by "taking the audience on a trip to remind everybody of all the cool stuff we've done for five years now. We wanted to relive the coolest moments on our show, so we came up this concept and it both honors what we've done so far and also propels the show for the rest of the season."

second season, revealed the episode would feature "all the [past] speedster villains" returning "wanting a piece of Barry".[6][3]

In mid-November 2018, The CW announced that the episode was titled "What's Past is Prologue", written by Helbing and Lauren Certo, and released the synopsis revealing that Barry and Nora would be travelling back in time to "gather some key necessities" to stop Cicada.[7] The episode's title was taken from a line in William Shakespeare's play The Tempest.[8] Two weeks later, Jessica Parker Kennedy revealed that in the episode Nora gets to see a special moment between her mom and dad "that like really breaks her heart". Patton added, "She gets to see Barry and Iris as we've known to love them over the past four seasons," with Parker Kennedy concluding that "the episode really brings the three of them closer."[9] Grant Gustin said the episode "felt like Back to the Future style time travel, seeing ourselves see ourselves in these other moments through a new lens. It was really cool."[10]

Filming

Filming of the episode began on September 26, 2018,[13] and concluded by early October.[14] Gustin thought it was great that they were able to have Cavanagh direct the episode, saying "[Cavanagh] took such good care; he understands the journey... we've found a lot of details that probably wouldn't have been found otherwise."[10]

Arrowverse tie-ins

In November 2018, it was revealed that the eighth episodes of The Flash,

Bunker Hill". The scene also confirmed Earth-90 as the earth for the Flash from the 1990 television series.[1] Marc Guggenheim, who acted as the showrunner for the crossover,[16] felt the tease was "cool because we've never... setup the crossover in the previous episodes before." The tease was meant to be one of two options for the "Elseworlds" cold opening. The writers could not choose which they wanted to use, with Guggenheim explaining someone decided to "take one cold open, move that and make that the post-credit tag, like the way The Flash typically does, at the end of all three shows, and then have the other cold open at the beginning of hour one." Supergirl co-showrunner Robert Rovner added that the tease was only supposed to air with The Flash's eighth episode, before being added to the other two episodes to make things easier for viewers since they "are coming to [the crossover] from our separate shows and we wanted something that [connects them together]."[1]

The time travel premise worked whenever the focus remained on Harrison Wells, but too much of this material played out as if Barry and Nora were watching a clip show of past seasons."[23]
