I'm the Girl He Wants to Kill - Thriller (1974)

Imagine being trapped in an office block at night, alone apart from a man who wants to kill you. This is the chilling and brilliantly realised premise behind this extremely suspenseful TV film from 1974.

Old Croydonian Brian Clemens, the brain behind The Avengers and The Professionals, created a series of stand-alone thrillers in the mid-seventies, called, erm, Thriller. It followed in the mould of Alfred Hitchcock Presents, each being a mini movie in its own right.

This one, I'm the Girl He Wants To Kill, is one of the most highly regarded of the series. Directed by Shaun O'Riordan it stars Robert Lang as the silent killer and Julie Sommars as his intended victim. I don't know where it's shot or what the building is - any leads gratefully received.

I wouldn't recommend watching this by yourself, it's claustrophobic and exhaustingly stressful, though brilliantly done. The YouTube clip is split into 7 parts, this should be a playlist that rolls between them all.
