Robert Newton gives a restrained and powerful performance as a cuckolded
doctor exacting revenge on his high-spirited wife by abducting her young
American lover, then keeping her guessing as to where he is, and whether he
is still alive. Sally Gray is nothing short of brilliant as the wife.
And,
Naughton Wayne is magnificent as the dogged police inspector. Obsession
combines brilliantly chiseled characterisations with an extremely
intelligent and literate screenplay. Keep it on tape, because no one gets
all the nuances the first time he or she watches it, but it's all put
together so brilliantly the repeat viewings become a glorious
pleasure.
