Assorted vocal cameos in Scream (2022)

Since high-profile uncredited vocal cameos could be added on exception basis, but there is still usually a high rate of declination, I would like to know what to do with unique situation that is the new Scream (2022) movie. A recent Fandom interview with directors Matt Betinelli-Olpin and Tyler Gillett, as well as executive producer Chad Villella confirm that in uncredited voiceover cameos:

• Matthew Lillard is heard three times: as a party guest with one line, toasting "To Wes" in the same scene and also as Ghostface in film-within-film Stab 8;
• Jamie Kennedy is heard twice in the party scene as a guest;
• Drew Barrymore is heard twice portraying the principal and toasting "To Wes";
• Also toasting "To Wes" as party guests are: Betinelli-Olpin and Gilllett themselves, Rian Johnson, Kevin Williamson, Henry Winkler, Hayden Panettiere, Adam Brody, Iya Labunka, Marco Beltrami, Patrick Lussier, Julie Plec, Gregory Plotkin, Sophia Takal and Lars Klevberg.   

My still pending submission #220126-175821-516000 is only five of those based on an incomplete read of the article. 

In addition yet to be added is a director commentary-confirmed fact that Scream 3 (2003) has Lillard and Skeet Ulrich reprise their roles as voices of Billy Loomis and Stu Macher, used through a voice changer.
