Hollywood tentpole movies and hit TV series as usual drove a host of fashion choices for ordinary trick-and-treating fans everywhere — young and old — on Tuesday.

But SAG-AFTRA‘s Halloween costume rules complicated fashion choices for striking actors as they were told by their union even after a backlash to avoid dressing up as Barbie and Ken or other superhero or sexy pop culture characters drawn from a struck studio project.

On Tuesday, Sarah Michelle Gellar took to Instagram to announce she and Freddy Prinze Jr. decided to scrap their Halloween costumes as fellow actors walked picket lines on the 110th day of a labor action between SAG-AFTRA and the Alliance of Motion Picture and Television Producers, which represents the major studios during ongoing contract talks.

“Normally this is when we would post our Halloween couples photo, but due [to] the ongoing strike, we had to scrap our original costumes. So, if you are out trick or treating tonight and see a very realistic Sarah Michelle and Freddie costume… it might just be us. See you next year,” Gellar wrote.

A flag-waving Don Lemon and partner Tim Malone on the former CNN host’s Instagram account stayed safe as they showed off respective Halloween costumes as Vice President Kamala Harris and President Joe Biden. Striking actors were reported to have dressed as generic ghosts, witches and vampires while walking a picket line outside the Los Angeles office of Netflix.  

But SAG-AFTRA didn’t have it all its own way with its Halloween restrictions on not dressing up as licensed studio movie or TV characters.

Megan Fox and Machine Gun Kelly took to Instagram to post photos of themselves dressed for Halloween as bloodied Kill Bill characters from Quentin Tarantino’s 2004 movie. Fox captioned her Instagram post “@sagaftra,” apparently to mock the actors union.

That drew condemnation from fellow actor Lisa Ann Walter, who took to X, formerly Twitter, to call out Fox for her fashion faux pas: “What a rebel. Keep posturing for stupid shit, pretty lady. Meanwhile we’ll be working 10 hours a day – unpaid – to get basic contract earners a fair deal”

While Fox dressed up as Gogo Yubari from Kill Bill: Vol. 1, that film was originally released by Disney division Miramax, but the rights to the classic revenge thriller were recently picked up by Lionsgate, which is not part of the AMPTP and plans a re-release of the Kill Bill movies.
