Harry Potter star Emma Watson quit university after reportedly being bullied because of her role in the film.
The actress announced last month that she was postponing her studies at Brown University to concentrate on other projects.
However Watson, who plays Hermione Granger in the franchise, is said to have become "frustrated" with the teasing she received.
According to the New York Daily News, fellow Brown students of Watson constantly taunted her with references to the film.
Watson has recently said that she feels sorry for Kate Middleton and all the pressures of the royal wedding.
