The BBC is offering fans the chance to take part in a special masterclass in Cardiff with Neill Gorton, director of Millennium FX and the man behind the creation of many of the monsters and aliens on Doctor Who.
The event is part of BBC Radio 4 Character Invasion, a project that will let people spend the day with the nation's best-loved characters. On Saturday 29 March 2014 writers' creations will take over the airwaves, invading Radio 4's programmes throughout the day, beginning with Tweet of the Day and through Any Answers? and Loose Ends. There will be public events at all BBC sites producing radio drama.
The Cardiff masterclass with Gorton will offer an insight into how some of some of television's best-loved monsters and aliens from Doctor Who and Wizards vs Aliens are created using cutting-edge prosthetics, animatronics and special make-up FX.
Tickets will be allocated through a random draw. To be in with a chance you need to register your interest on the BBC website by 4pm on Thursday 13 March. You can apply for a maximum of four tickets per household. It should be noted, though, that as this is a free event, the allocation of tickets does not guarantee entry.
Additional Character Invasion events are taking place in Belfast, Birmingham, Bristol, Cardiff, Glasgow, London and Salford.
