In a Variety interview, Barrera said Mason Gooding and Jasmin Savoy Brown were "one hundred percent" scabby for joining Scream 7 without her.

The fallout also saw Jenna Ortega leave and director Christopher Landon step away, while Barrera said private support from industry figures meant little without public action.
