Two stars of the Harry Potter films, including actress Emma Watson, were each banned from driving for six months yesterday after being caught speeding in separate incidents. Watson, 35, who played Hermione Granger, the friend of Potter in the movie franchise, was banned for driving at 38 miles an hour in a 30-mile zone in southeastern Banbury last July. Zoe Wanamaker, 76, who played Quidditch teacher Madame Hooch in Harry Potter And The Philosopher’s Stone, was banned for six months for her offence. She had been caught driving at 46 miles an hour in a 40-mile zone of the M4 motorway in Berkshire last August.
