All joking aside, if Gaga were to play the Witch, that movie would have a HUGE opening. Then if it's actually GOOD on top of that, you have a big hit on your hands.
To me, it comes down to "Stay With Me." That's where the Witch really has to sing AND act. The rest is "show" and "smoke" and "mirrors" (sometimes quite literally). I also think whoever plays the Witch will want to do BOTH sides of her: ugly and pretty. That's what makes it a showy role. Not just one side. But I also think it's an interesting idea to have two actresses play her. In a film, anything is possible, including morphing them together at one point (voice of one, body of another, etc.).
I wouldn't put it past them to see the Witch as the role to bring people in. Either a huge movie star or recording star. Then they'll cast the other parts around her. And no, GaGa at 25 is not too young for the Witch, once she is revealed to be pretty. (But is she pretty enough? Answer: It's Lady Gaga, so who cares?)
