''They don't love it that I occasionally have to take off certain items of clothing. We sort of have an unspoken rule of, if my character on House of Cards or during a photoshoot, I have to be in my underwear or something, I sort of send out a family text about it: 'Beware of the first 30 seconds of House of Cards, you will be disturbed'." Actress Kate Mara has vowed to warn her family about risque photoshoots and saucy film and Tv scenes.
