Incredibly Smart Celebs Who Played Really Dumb Characters

19. Jayne Mansfield

Jayne Mansfield was known for constantly playing a role. When she arrived in Hollywood as a beautiful blonde, she was automatically typecast as the ditzy blonde. She was played in the shadow of Marilyn Monroe and always kept up appearances of being a dumb, naïve blonde. She was reported to have a 160 IQ and speak five languages, but she never let that part of her persona show. Her daughter Mariska Hargitay has taken a very different approach to acting.
