At the end of the film it is stated that Lowry refused both an OBE and a Knighthood in 1968. This isn't quite true. He turned down an OBE in 1955, a CBE in 1961, a Knighthood in 1968, and a CH (Companion of Honour) in 1972 and 1976. He is believed to have turned down more honours than anyone else.
Mrs Lowry describes the house they live in as a "2 up 2 down"giving the impression it is a pokey and cramped inexpensive place. In real life the actual house in Pendlebury was quite spacious with six rooms.
L S Lowry is shown as having exhibited Going to Work in 1934. In reality, he didn't paint it until 1943.
One of the records played during the film in 1934 was 'Das Lied von der Erde' by Mahler. The singer are (according to the credits) Charles Kullman and Kerstin Thorborg with the Vienna Philharmonic Orchestra conducted by Bruno Walter. This recording was made in1937.
In the scene where Mrs Lowry rips up the letter, she is later seen lying against her bed pillows. The pillow on the left of the screen (her right) clearly shows a modern style label poking out through the slit in the pillow case.
