Pink String and Sealing Wax is a 1945 British drama film directed by Robert Hamer and starring Mervyn Johns.

Pharmacist Sutton, a strict, arbitrary father, scolds his son David (Gordon Jackson) for writing love verses instead of seeing to business at the pharmacy.

Later, Victoria and Peggy, forbidden from seeing a popular opera singer's concert, decide to wait outside the stage door.

The singer invites them to supper and arranges for Victoria to attend an audition at London's Royal College of Music.

However, after Joe's burial, a police inspector informs Pearl that her husband's body is to be exhumed for a post mortem.

However, Sutton sees through the ruse and reveals that it was his expert opinion to the police that caused her dead husband's exhumation in the first place.

She is at first furious, then starts to weep, but gets little sympathy from Sutton, nor from the man she loves, who abandons her the moment it is certain that Pearl cannot avoid arrest for murder.

The film premiered in London on 3 December 1945 at the Tivoli Cinema on The Strand and the Marble Arch Pavilion.

The critic in The Times praised Googie Withers and Gordon Jackson for their roles, and concluded that Robert Hamer, "has made, in spite of occasional lapses and longueurs, a promising beginning as a director.
