There is a live action Snow White I'm looking for, there is one distinct scene that stands out. The delivery of the poisoned apple.

The apple was cut in half, half the apple was poisoned, and rejoined. So, when the Queen finds Snow White, she offers the apple and when she gets questioned she offers to share it. Cuts it in half, Snow White chooses the non-poisoned half, but there is apparently a worm in it and they end up swapping halves. And the rest of the story goes on.
