The best Rob Brydon’s documentary movies

In 1995, Stephen Fry was performing in Simon Gray's West End play, "Cell Mates." After three days, he walked out of the production. Sitting in a garage, his hand on the car ignition, he contemplated suicide for two hours, before fleeing his home country for the European mainland. It wasn't until this frightening episode that Fry was diagnosed with manic depression, or bipolar disorder, a psychological condition that sees its sufferers oscillating dangerously between dizzying heights of mania and gutting troughs of prolonged depression. This 2 part documentary unfolds like a personal journey of self-discovery. Fry confronts his medical condition by consulting experts and others who have suffered the disorder (including Richard Dreyfuss and Carrie Fisher). This is a valuable documentary, and, having been acquainted only with Stephen Fry's bubbly TV persona, a fascinatingly intimate character study.

Prairie dogs are America's answer to the meerkat - small, sociable and exceptionally cute. This offbeat film narrated by Rob Brydon takes us to the Wild West where prairie dogs live in huge colonies known as 'towns'. Like meerkats, they are comical to watch, but there is a whole lot more to prairie dogs than just being cute - they can talk. For 30 years Professor Con Slobodchikoff has been recording their calls in response to predators like coyotes, hawks and badgers. He believes he has discovered a language second only to humans in its complexity. It's a bold claim but is he right? Con has devised a series of cunning field experiments to help prove his point.
