Patrick Hamilton's play Gas Light was a huge hit in when it opened in 1938, so it's hardly surprising that this hit film was turned round so quickly. Although not opened up far beyond its theatrical origins, director Thorold Dickinson did a remarkable job evoking a terrifying, gothic and very cinematic world.
The film was famously suppressed by American studio MGM when they made their own version of the film starring Ingrid Bergman and Charles Boyer. As a result, Dickinson's British original has always been overshadowed by it's Hollywood rival - and it's always been far more difficult to get to see.
For anyone who likes their thrillers dark, dangerous and sadistic, this delivers in spades - not unlike Hitchcock at his best. It feels more tense, cruel and adult than George Cuckor's remake and revels in its overripe, melodramatic Victorian setting.
This newly remastered version looks and sounds exceptional. As always with the BFI's label, there are a wide range of extras. Some of these seem a bit esoteric and eccentrically chosen, but should appeal to people who are particularly interested in finding out more about Dickinson's documentary-making career and provide a glimpse of life at the time Gaslight was made.
