The other Burke & Hare movies my correspondent mentioned were:

The Flesh & the Fiends (aka Mania) from 1960, which stars George Rose, Donald Pleasance and Peter Cushing as Burke, Hare and Knox respectively. The Radio Times Film Guide calls it "an unflinching shocker".

The Doctor & the Devils (1985), produced by Mel Brooks from a forgotten Dylan Thomas screenplay. The Burke, Hare and Knox equivalents here are played by Jonathan Pryce, Stephen Rea and Timothy Dalton respectively. Patrick Stewart, Beryl Reid and Sian Phillips all put in an appearance too. "High on period detail, but low on Grand Guignol chills," says the RT guide.
