London: Actress Emma Stone says she felt pressurised while working on "The Help" as the film is based on a book which is one of her mother`s favourite.
The 22-year-old plays a journalist named Eugenia Phelan in the movie, based on Kathryn Stockett`s best-selling novel with the same name.
"There`s an extra-weight of responsibility (because the book is so popular). To make matters worse, it`s my mom`s favourite book. That`s the definition of pressure, right there," contactmusic.com quoted Stone as saying.
