Perhaps the oddest thing about The Mutations is that it is directed by the former Oscar-winning cinematographer Jack Cardiff. Cardiff had a highly respectable curriculum vitae, having lensed like Michael Powell classics A Matter of Life and Death/Stairway to Heaven (1946), Black Narcissus (1947) and The Red Shoes (1948) and other works such as Pandora and the Flying Dutchman (1951) and The African Queen (1952) where he became famed for his epic work with Technicolor. Cardiff had also directed a handful of titles with the acclaimed D.H. Lawrence adaptation Sons and Lovers (1960) and the first Smellovision film Scent of Mystery (1960).
The Mutations is a strange recapturing of Freaks (1932), casting real human deformities as the mutated creatures at the circus. Although the tastelessness with which characters crack puns about the various human deformities certainly puts the film into dubious regard. Certainly, Jack Cardiff fails to imbue the deformities with any of the pathos that Tod Browning did in Freaks.
The Mutations is a bad film Jack Cardiff directs at a tedious pace and the plot is so uninvolving that nobody could care less what happens. Even the usually reliable Donald Pleasence fails to enliven his part, which seems to mostly consist of reciting dialogue from scientific textbooks. Ken Middleham, best known for his insect photography on The Hellstrom Chronicle (1971) and Phase IV (1974), contributes some modest time-lapse photography. The film also features Tom Baker as the circus master, just prior to Baker being cast as the fourth incarnation of Doctor Who (1963-89, 2005 ).
