I rewatched this with my little sister last night and I really don’t get why they did it.

I know they were desperately trying to launch Sara Paxton then. But it would’ve honestly worked fine to just cast her as young Debbie Reynolds. In that re-watch, if anything, I felt like it was more confusing for little kids that she played both Marnie and Agatha.

I always think about how it must have been being Debbie Reynolds or one of the other actors too - all showing up and reuniting on set and the main actor is just not there and replaced by someone else.
