Twisted Nerve

Hywel Bennett stars as Martin Durnley, a rich but damaged Oxford University drop-out with a hatred of his banker stepfather, played by Frank Finlay. His mum babies the boy, a consequence of Martin's elder brother, a Down Syndrome sufferer (or 'Mongoloid' - or even 'mentally backward' as they say here), being in full-time care, and the doctors having warned Martin's parents not to have any more children - just to be on the safe side. Too late: troubled mummy's boy Martin, with his cuddly toys and penchant for smashing his own reflection, appears to have proved the doctors misgivings.Twisted Nerve featuring Hayley Mills and Hywel Bennett is not currently available to stream, rent, or buy but you can add it to your want to see list for updates.
