In his 1983 fake documentary 'Zelig', Woody Allen plays a character, Leonard Zelig, a kind of human chameleon who takes on the appearance and behaviour of whoever he is with. Now psychologists in Italy have reported the real-life case of AD, a 65-year-old whose identity appears dependent on the environment he is in. He started behaving this way after cardiac arrest caused damage to the fronto-temporal region of his brain.

When with doctors, AD assumes the role of a doctor; when with psychologists he says he is a psychologist; at the solicitors he claims to be a solicitor. AD doesn't just make these claims, he actually plays the roles and provides plausible stories for how he came to be in these roles.

To investigate further, Giovannina Conchiglia and colleagues used actors to contrive different scenarios. At a bar, an actor asked AD for a cocktail, prompting him to immediately fulfil the role of bar-tender, claiming that he was on a two-week trial hoping to gain a permanent position. Taken to the hospital kitchen for 40 minutes, AD quickly assumed the role of head chef, and claimed responsibility for preparing special menus for diabetic patients. He maintains these roles until the situation changes. However, he didn't adopt the role of laundry worker at the hospital laundry, perhaps because it was too far out of keeping with his real-life career as a politician...
