Sure even commercial or small budget movies need good actors but with art movies, that is the only thing there is.
for example, OSO didn't need good actors because the movie demanded nothing out of them.
on the other hand, a movie like water-- the only story lies in how the actors act because otherwise there are no songs, or glamor to take the attention away.
All of her movies so far, LAK, OSO, Bachna Ae Haseeno-- she hasn't had a chance to showcase her talent because all of those roles are not demanding... Now if she does a movie like Omkara, or Kaminey (they are not art but as close to it as you get) then yah, maybe she can say she doesn't need an art movie to prove herself.
