Emma Watson says The Circle brought home pitfalls of social media

Watson stars in a movie about how social media giants control and monitor personal information.

NEW YORK: Emma Watson says making her new movie The Circle, about a fictitious social media giant, had been a tough and vulnerable experience that brought home issues of ethics and the boundaries of privacy in an increasingly public age. 

Watson, 27, grew up in the public eye as a child actress in the Harry Potter movies, but the British star said she had not fully considered the implications of mass data collection, online activities, and personal freedom before making The Circle.
