Maggie Gyllenhaal is a secret sufferer of claustrophobia.
The Dark Knight actress has revealed she fears small spaces but has managed to conquer her terror of certain areas thanks to her seven-year-old daughter Ramona.
However, despite making progress throughout the years, Gyllenhaal still has some issues when it comes to coping with confined spaces.
She tells The Observer Magazine, "I'm claustrophobic. It's taken me years to be Ok on the subway, but in taking my daughter to school I've conquered it. Don't even talk to me about elevators."
