Ironic casting?

I can't stand Kenneth Branagh, but THR informs me that Helena Bonham Carter is going to play the fairy godmother in his upcoming adaptation of Cinderella, which I am now obliged to see. The movie will also feature Lily James in the title role (no one cares) and Cate Blanchett as the wicked stepmother. I like Blanchett, but I find the idea of Bonham Carter—who, in my head, always dresses like this, even while going to Target or whatever—playing a magical pretty-dress dispenser too delightful to resist.
