Kelly MacDonald: Mum visited Trainspotting set on day I shot sex scene

ACTRESS Kelly Macdonald has told how she “naively” invited her mother and brother along to watch her steamy sex scene with Ewan McGregor in Trainspotting.

It is loosely based on the Edinburgh-born author’s novel Porno, set about 20 years later, and the Diane character has a brief role.
