The station was actually filmed at Aldwych with ex-Northern line 1972 stock which caused continuity errors as deep-level trains and tunnels were used when the District line is sub-surface.
Stationen blev faktisk filmet på Aldwych med tidligere Northern line 1972-materiel, der forårsagede kontinuitetsfejl, da dybtliggende tog og tunneller blev benyttet, mens District line er under overfladen.
