A Liverpool bingo caller finds himself in the middle of a murder case

This crime drama features the full hat-trick of Liverpool railway termini, in one film! Lime Street station features most prominently, with a train of blue & grey-liveried Mk1 and Mk2 coaching stock departing in one shot. In the background to this scene parcels vans are present and they include a very vintage Gresley brake. There then follows a scene onboard the train. Later shots were taken at both Central and Exchange stations, in their final years of operation. Finally, there are scenes filmed on the Piccadilly Line of London Underground at Aldwych, Holborn and Russell Square stations featuring 1959-built tube stock.

Albert Finney at Liverpool Central, which closed less than a year after this film was released. The deep-level underground station is still open, however, on Merseyrail’s subterranean network.
And this makes up the trio of Liverpool termini open at the time of filming. This is Liverpool Exchange which remained open until April 1977.
Arriving at a London Underground station, Albert Finney makes his way down to the platforms. This is a relatively rare glimpse of the booking hall at Aldwych.
Down on the platform now at Aldwych and Albert Finney is being watched closely by Fulton Mackay.
