Mrs. Doubtfire (1993)
The scene where Mrs. Doubtfire had to cover her face with icing didn't go as planned. When the icing started dripping down the actor's face because the heat from set lights made it melt, Robbie Williams had to improvise. At the moment when the icing dripped into Mrs. Sellner’s tea, he decided to say, “There you go, you’ve got your cream and your sugar now.”
