Three schoolgirls have been chosen to star in the new Harry Potter film tipped to be a top-grossing flick.

Beaconsfield High School pupils Danni Tabor, 15, Natalie Klamar, 15, and Samantha Whittaker, 16, were picked from hundreds of hopefuls.

The three, who also go to Redroof Stage School, Maidenhead, have had letters to say they are in the film. Two of them were called for audition on Friday and asked to perform cartwheels and forward and backward rolls.

Danni said: "They were checking if we were flexible because I think we'll be cast as witches who fly on broomsticks in the sky."

Natalie Klamar said they are all excited but are also in the middle of their GCSEs. She added: "I have just started to read the books because everyone is raving about them so it is quite exciting."

Samantha Whittaker has been at stage school for four years but this is her biggest break.

Deputy head of Beaconsfield High School Dave Preston, said: "Performing arts are quite strong in the school and as well as performing in school productions there are a number of pupils who are members of stage schools. It is particularly exciting for the three girls involved because they are involved in such a high-profile production."
