Considering this is set in a high school, wouldn't there be potential minors in this scene? I know that the girl who plays Wednesday is over 18, but that doesn't account for the others.

I couldn't guarantee it. But I'd be surprised. Having watched the series just for entertainment, not want, all the named cast members were in there 20s despite supposedly being in a "school".

I was honestly surprised at just how much I liked the Netflix "Wednesday" series. Addams Family has always been fine, but I never really got how they could exist in the world. Establishing the concept of the "Outcasts" added a verisimilitude to the world (and actually made the Films better) in my opinion. Fun stuff.

I can't imagine they would have minors here...there are so many rules for them for schools and hours, which is why they cast 18 if possible. And no way are they going through that hassle for extras.
