JUNO Temple, a former Somerset student, has won the Rising Star Award at the BAFTAs.
Ms Temple starred in the Batman movie The Dark Knight Rises and previously appeared in other high-profile films, including Atonement, alongside Keira Knightley, Notes on a Scandal alongside Cate Blanchett and Dame Judi Dench, and The Other Boleyn Girl, which stars Scarlett Johansson and Natalie Portman.
Speaking after collecting the gong, Ms Temple said: "Thank you to BAFTA for this huge honour and including me on this list of such wonderful actors."
She joked that her younger brother Felix got the whole of his school to vote for her.
