Mamma Mia! Here We Go Again

so here’s my main issue with this movie: stellan skarsgard has eight kids, four of whom are actors, and they cast an outsider as young bill anderson!!! now i understand that alexander is 40 and that bill is too pennywisey to be in fun movies but did you know there’s a 22 year old valter skarsgard? the one im banking on marrying to sneak my way into the skarsgard empire? if you’re not gonna cast the actual spawn of stellan why wouldn’t you do what you did in the first movie and just put the older actors in young wigs and makeup and pretend they’re 20? i have many grievances already but this is top priority
