Neve Campbell dropped out of the latest new Scream sequel over a pay dispute earlier this year.
Weaving and Revolori will be joined by another series newcomer, My Best Friend’s Wedding star Dermot Mulroney.
Gale Weathers, the fan-favourite news reporter played by Courteney Cox in the original film, is the only member of the 1996 cast so far confirmed to return for Scream 6.
The actor has played lead character Sidney Prescott in all five previous entries of the hit horror franchise, most recently in this year’s Scream. Campbell’s exit, which earned support from her original co-stars, creates a hole at the centre of the series that Sidney has filled since the first Scream movie was released in 1996.
