Sinopse: Wizards vs Aliens is a science fantasy television series aimed at children. It is produced by BBC Wales and FremantleMedia Enterprises at the newly opened BBC Roath Lock Studios in Cardiff for CBBC and created by Russell T Davies and Phil Ford. The series focuses on 16-year-old wizard Tom Clarke and his scientist best friend Benjamin "Benny" Sherwood as they battle the forces of the alien Nekross, who have invaded Earth with the intent of consuming anything and anyone connected to magic. 26 episodes of the drama, spread over two years and two series, have been commissioned, although co-creator Russell T Davies says that it could continue beyond that, and could 'easily run for ten years'. The first series, consisting of twelve 28-minute episodes, premiered in 2012. In production terms, Wizards vs Aliens is, in effect, the replacement for The Sarah Jane Adventures, also created by Davies, which was ended due to the death of its lead actor Elisabeth Sladen. Other writers working on the show include Gareth Roberts, Joseph Lidster and Clayton Hickman. Originally announced as Aliens vs Wizards, the title was changed to "Wizards vs Aliens" on legal advice.
