DVD: Berberian Sound Studio (15)

Toby Jones's timid sound technician, Gilderoy, has been recruited to work on a ripe Italian horror, The Equestrian Vortex.

At first, he's anxious that his travel expenses won't be reimbursed but far more damaging horrors lie in wait for this fastidious Brit. The first third of Strickland's consistently unnerving thriller contains some beautifully observed visual gags about low-budget slashers, but in the final third the cramped studio space really starts to unsettle poor Gilderoy and us. Blow Out and The Conversation are obvious comparisons, but this absorbing work is far odder than both.
