 At the beginning of the scene when Augustus Gloop is being  introduced as the first golden ticket finder and the reporters head  is still framed by the antlers on the wall, Diana Sowle, who plays  Charlies mother, walks from right to left behind the reporter and  gives him a brief quizzical look just before moving out of frame.  Shes cleaned up, wearing makeup and a stylish (for the time) green  dress, so shes clearly not appearing as Mrs. Bucket in this scene.
