From Deadpool to Ghosts? Ryan Reynolds' Hilarious Halloween Dilemma

To drive this home, the union also stated that members can "dress up as characters from non-struck content, like animated TV shows." By this, SAG-AFTRA means that members can dress as characters from studios that don't employ their services, such as animated studios.

SAG-AFTRA did give a loophole for actors who can't wriggle their way out of the forbidden costumes, though, and it is to not post them on social media.

SAG-AFTRA's Halloween rules are part of the union's strategy to deny promotion to projects by AMPTP members, including on red carpets and press junkets, and force them to the negotiating table. When the strike began in July, Oppenheimer's cast members staged a walkout during its premiere in keeping with that rule.

The union's Halloween rules are its latest attempt to stick to that tactic and ensure that no AMPTP studio is promoted by screen actors, even indirectly.

By the way, Reynolds isn't the only actor who has a problem with the guidelines. Mandy Moore, known for her role in This Is Us, voiced her concerns on Instagram, urging the union to "get back to the table" and negotiate an end to the strike.

Former union president Melissa Gilbert also broke ranks and criticized the guidelines on her Instagram page, questioning their effectiveness in resolving the strike. She wrote, "THIS is what you guys come up with? Literally no one cares what anyone wears for Halloween. I mean, do you really think this kind of infantile stuff is going to end the strike? We look like a joke."

Given Moore and Gilbert's comments, one would think that SAG-AFTRA has been unwilling to negotiate an end to the strike. However, that is not the case. Just last week, AMPTP representatives walked out on negotiations with the guild barely a week AFTER agreeing to return to it.

SAG-AFTRA representatives have since implored the AMPTP to continue negotiations, stressing that they are willing to find a common ground. Unfortunately, the AMPTP seems determined to frustrate these efforts and has taken a "My way or the highway" approach to proceedings.

Granted, SAG-AFTRA's Halloween guidelines seem juvenile. But one can certainly understand the union's frustration with the major studios and its determination to use every weapon in its arsenal to force an end to the standoff.
