Residents picked up on the film crew in their area when the cast were seen on location in The Rivoli Ballroom. Originally opened in 1913, it is the only intact 1950s ballroom remaining in England. It is famed for its original decor and interior fittings and is often used as a location for films, TV and music videos. Further promo shots for Luther show Cornelius (played by Patrick Malahide) and some balaclava-ed baddies getting down to some nasty business in the ballroom.
