In 1997, Blair reunited with director Wes Craven for a cameo role in "Scream" (1996), and also starred in a Broadway revival of "Grease", playing Rizzo. The same year, she appeared in a documentary for Channel 4 in the United Kingdom entitled "Didn't You Used to be Satan?", which served as a biography of her life to that point and how the film "The Exorcist" had dominated her career and life. She also appeared in critic Mark Kermode's 1998 BBC documentary "The Fear of God" (which Kermode directed and hosted), included as a special feature on the DVD of "The Exorcist". Most of Kermode's linking scenes to camera were removed from the DVD version to shorten the running time. The version shown on BBC TV in 1998 was shown intact. The following year Blair appeared in an online parody of "The Blair Witch Project" titled "The Blair Bitch Project".
