(FILES) British actor David Walliams poses during a photocall for the serie "Partners in crime" during the MIPTV, on April 13, 2015 in Cannes, on the French Riviera. Britain's world-renowned entertainment sector is facing mounting calls to usher in sweeping reforms and greater oversight, amid a fresh slew of rape and sexual abuse allegations against some of its powerful male stars. Comedian and ex-Hollywood actor Russell Brand was on November 9, jailed for over 10 years for rape and sexual assault against four women dating back to the 2000s, including raping a fan and abusing female staff from media organisations where he worked. A day later a Guardian newspaper investigation reported that his friend, fellow comic and bestselling children's author David Walliams, sexually assaulted a 15-year-old budding comedy writer, and harassed young female colleagues. He has denied the accusations. (Photo by Valery HACHE / AFP via Getty Images)
