Title of recent draft is "Sister Act 3: Old Habits Die Hard".
In an interview on ITV's Loose Women (1999), Whoopi Goldberg made a public plea to Maggie Smith that the role of Mother Superior was being held just for her and could not be played by anyone else. Whoopi expressed her willingness to accommodate Maggie; now in her late eighties; by moving production to the United Kingdom if necessary to make things easier for her.
Currently slated for the Disney+ streaming service.
Cast members of the first two films unable to return include the late Mary Wickes (Mary Lazarus), Ellen Albertini Dow, Carmen Zapata, Pat Crawford Brown, Susan Johnson, Ruth Kobart, Susan Browning, Edith Diaz (Choir Nuns) and Rose Parenti (Sister Alma).
Whoopi Goldberg met Pope Francis and found out that he was a Sister Act fan. When Whoopi invited the Pope to make an appearance in this movie, Francis said he was open to the idea, but it would depend on his schedule.
