A film adaptation of Wicked had been discussed since 2004, though producers were waiting for a dip in the stage musical's earnings. By 2012, Universal Studios was reported to be producing the film with Stephen Daldry as director and Winnie Holzman, who wrote the musical's book, to pen the screenplay. Universal announced in 2016 that the film would be released in theaters in December 2019, with Daldry still attached to direct it, and the script to be co-written by the musical's creators, Holzman and Schwartz. In May 2017, Schwartz stated that the film would feature "at least two" new songs. On February 8, 2019, Universal announced a new release date of December 22, 2021, for the Wicked film.
- This is the 2nd Oz movie to be based off a broadway musical after The Wiz.
- It was reported in 2011 that ABC (owned in part by Walt Disney Pictures) had plans to "strictly adapt" the novel as a miniseries and to remove elements of the musicial. It is unknown if this is still forthcoming since the televison series Once Upon a Time has introduced its own Oz based storyline. It is to be noted that ABC owns the rights to the book which they brought in 2009, it currently is unknown if a legal dispute may occur because of this.
