Filming for the BBC's Doctor Who, Torchwood and Sarah Jane Adventures TV series takes place mostly in and around Cardiff. The city stands in for London and various alien worlds though the iconic Torchwood hub is 'officially' located in Cardiff Bay's Mermaid Quay, or at least it was until they blew it to smithereens. 

In the most recent Torchwood series (2011)  the film locations are split between the USA and South Wales. Filming for the current set of Matt Smith Doctor Who episodes is currently taking place so you might spot some familiar faces in the Welsh Capital once again.
