Residents of Port Talbot are being warned to expect smoke, and lots of 'emergency vehicles and emergency workers in town this week.
But there is no need to panic - there is no major incident - at least not a real one anyway. The smoke, and emergency vehicles will all be fake, with actors playing the roles of emergency workers. They will be there for filming work carried out for BBC One. Whilst the actual programme being filmed has not been announced publicly, it's understood that the scenes will be part of an upcoming episode of a "long running BBC drama" - so you can probably have a good guess at which one.
Cameras will be rolling between 11am and 9pm on Monday, February 20, with further filming taking place on Tuesday, February 21, and Wednesday, February 22. Neath Port Talbot Council has advised that the filming is set to take place near Aberavon Green Stars RFC. The production team at BBC One have said they wish to advise local residents that their filming "is not a real emergency" and therefore people should not be alarmed if they see smoke and a seemingly high presence of emergency services personnel.
