DOCUMENTARY OF THE WEEK
1/2. Robbie Williams , Carrie Fisher , Tony Slattery and Rick Stein join Stephen Fry as he explores the world of bipolar disorder - a mental illness that affects up to four million people in the UK. What triggers it and why does it take, on average, a staggering nine years to diagnose? Motivated by his own diagnosis - which came 11 years ago, after a suicide attempt - Stephen sets out to uncover more about a greatly misunderstood condition which drives those who have it from extreme highs to crippling and often suicidal lows.
Director/Producer Ross Wilson Case Notes, at 9pm on Radio 4, also focuses on bipolar disorder Fears of a clown: page 31
PICK OF THE DAY STEPHEN FRY: THE SECRET LIFE OF THE MANIC DEPRESSIVE A moving exploration of a disabling psychological disorder
DOCUMENTARY OF THE WEEK Stephen Fry: the Secret Life of the Manic Depressive 9.00pm BBC2 After Stephen Fry walked out of the West End theatre production of Simon Gray's Cell Mates he went to his garage, sealed the door with a duvet and sat in his car, his hand hovering for two hours over the ignition key.
A later diagnosis revealed Fry was bipolar, or a manic depressive. Here, in a profoundly moving, ruthlessly honest two-part documentary, he talks to others similarly affected. And he looks back on his own life for any early signs of what can be a debilitating psychiatric condition. Fry returns to his public school, Uppingham, which expelled him after episodes of compulsive stealing, and to Pucklechurch Prison, where he was held after being convicted for credit-card fraud.
Fry conducts revealing interviews with bipolarfriends, including Carrie Fisher and Tony Slattery, who articulates quite beautifully (if that's the right word) what it feels like to be at the mercy of a mind in turmoil. But it's the people who aren't famous who are the most affecting, struggling in anonymity with a dreadful affliction. Alison Graham Fears ofa a clown: page 31
