TV crews and acclaimed actor Idris Elba are in Walthamstow today shooting what is believed to be a new episode of BBC crime drama Luther.
Scenes are being shot in an industrial unit in Vallentin Road and other areas around Wood Street.
Production staff at the scene declined to comment or reveal further information, but actors including Mr Elba have been spotted by the Guardian.
He has starred in a string of Hollywood films including Prometheus and Thor, but is arguably best known for his role as Stringer Bell in cult US crime drama The Wire.
The third series of Luther, a psychological crime drama on BBC1, is expected to be broadcast later this year.
Another upcoming high-profile performance for Mr Elba, who grew up in Canning Town, east London, is his starring role in Nelson Mandela biopic 'Mandela: Long Walk to Freedom', also due out later in 2013.
Other TV shows partly filmed in Walthamstow in recent years include comedy programme The Inbetweeners, at the now-closed Standard Music Venue, and sci-fi comedy drama Misfits at Waltham Forest Town Hall.
