I'm not familiar with Fountain, but the "!~" is a "doesn't match
this regexp" operator, so I'm surprised it's folding them
away rather than folding away all lines that *don't* begin with an
"=".

You should be able to do

setlocal foldexpr=getline(v:lnum)!~'^[=#]'

to use a character-class. If they can begin after arbitrary
whitespace, you could also do

setlocal foldexpr=getline(v:lnum)!~'^\\s*[=#]'
