The starlet told Fallon that she couldn’t have gone to college without the help of Robin Williams (even thought the two have never met), how she wore a Mickey Mouse costume to pay the bills before her acting career took off, and why she intentionally tried to freak her friends out after starring in the new horror flick Mama.
