MTA - Model Turned Actor (C4) - The premise for this two-part documentary is simple: Twenty models attempt to become professional actors in three months.

I expected the latest Pop Idol/Soapstars variation in which unknowns are turned into manufactured, saleable products and ended up watching In The Psychiatrist's Chair.

The participants looked as shocked as I did as acting coach Kate Marlow spent classes delving into the minds of would-be performers rather than explaining the Stanislavsky method. The result was TV of the most voyeuristic kind, culminating in one distressed student confessing, after incessant prodding by interrogator Marlow, that she had been raped.

The models who wanted to be known for their acting rather than their looks had paid £800 for the 20-day course, which probably worked out cheaper than a series of sessions on the shrink's couch.

Camilla Storey runs The School of the Science of Acting with a tough set of rules. Models were required to stop smoking, shave off facial hair and remove all piercings. They were warned that lateness would result in expulsion. From cruising the catwalks looking good, they went to acting boot camp and feeling bad.

Marlow, we learned, was "known for her incisive approach". Her constant probing of their psychological make-up proved wearisome. As one of them put it: "I want to be a good actor not a good patient."

In the end, they rebelled with Storey having to act as mediator between teacher and class. A kind of peace was restored although Marlow remained unrepentant about her methods aimed at opening up awareness into why they behave like they do.

Full-time students staged a show for the models to prove the school's approach does work. But, if I'd been one of hopefuls, I'd have asked for my money back after the glimpses of the awful performance we saw.
