Emma Thompson, 63, has completely transformed for her new role as the iconic nasty teacher Miss Trunchbull in Matilda the Musical.The new Netflix project features the Love Actually actress in one of her least recognisable roles to date, but the nasty teacher has also had some changes since she last appeared on screen in the original Roald Dahl movie back in 1996. At the time, Miss Trunchbull was played by Pam Ferris, and wore a navy uniform throughout her scenes as principal, later putting on her Olympics jumper and trousers for the shot-put throwing.The new Trunchbull is more of a traditional-style schoolteacher, wearing a khaki and brown military-style coat over the top of a shirt and tie.
