But apart from that, an actor being asked about a scene they acted and reacting with "I don't know what that is. I don't know, I don't have a clue, I don't care" is a bit ridiculous. Everyone realizes that the phone and its messaging software is completely irrelevant to the movie, but we are used to great actors taking pride in details no layman would notice. Imagine a James Bond actor stating he doesn't care about the watch he wore, or Keanu Reeves mistakenly wearing the wrong type of belt for a suit and answering with "I don't know anything about belts, and I don't care"
