Travel deep under the surface of the sea, as the officers and crew of HMS Goliath invite you to share in 'Deep Trouble'.

All four series of the hilarious historical sitcom set just before and during the American Revolution. Baltimore, 1770, and shopkeeper Samuel Oliphant has much to worry about. Storm clouds are gathering, business is bad and to make matters worse, he’s been forced to play host to two British soldiers. Hapless officer Captain Brimshaw is decent enough, but his fellow redcoat - the one-eyed, one-eared, one-armed and one-legged Sergeant McGurk - is a shameless rascal obsessed with money and sex.

The story so far: unfortunately, Burrows, the leader of the colony, has died on the voyage, so his number two, Brian (Nicholas Lyndhurst), is now in charge. He's a nice enough chap but no alpha male, and his desire to sort things out with a nice friendly meeting infuriates the colony's chief physician, Lillian (Vicki Pepperdine), who'd really rather everyone was walking round in tight colour-coded tunics and saluting each other. She's also in charge of Project Adam, the plan to conceive and give birth to the first colony-born baby.

Sir John Woodstock (James Fleet) is the Lord of the Castle and basically in charge of keeping order in the ramshackle medieval village. Although he hates all that torturing and usually lets the peasants off with a bit of community service. He lives in his huge but slightly falling down castle (but then it was built by the French, so what can one expect) with his daughter Anne (Martha Howe-Douglas) and very teenage son Henry (Steven Kynman). Anne’s best friend Charlotte (Ingrid Oliver) nearly always joins Anne on her constant quest to find fit men in the village. 

John Fuller-Carp, the Machiavellian head of chambers at Forecourt Buildings, is determined to become a QC and will perform almost any moral contortion to achieve his goal. When left-wing Ruth Quirke, rumoured to be a High Court judge's daughter, applies to join his chambers, Fuller-Carp's imagination goes into overdrive and promotion seems inevitable. However, his attempts to project a 'New Labour' image cut no ice with Ruth, and the two are soon at each other's throats. 

Reporters Charlie Palmer and Moog Johnson are supposed to be exploring the galaxy in search of unimaginable news. But the beauty of an infinite universe is that if everything possible happens somewhere, there's no need to actually go there to check. So they may as well stay where they are - parked on Clapham Common disguised as a hedge - and simply make up their stories instead. Unfortunately, their terrifying boss at Inter-Galactic News, Korg, is on to them and won't tolerate their fake news any longer. 

Rod Millet has always dreamed of working at the Maltby Collection, but on being appointed Deputy Curator of Painting and Sculpture, it quickly becomes clear that the son of a self-made biscuit mogul isn't going to fit into the musty, insular world of London antiquities. But when, on his first day, Rod learns that the museum has been earmarked for closure, he starts a campaign to save it (threatening his boss Walter Brindle’s plans for a cushy early retirement). With the collection’s future secured, the staff turn their energies towards romance. 

One of the main movers and shakers at TS Sports Stars agency, Trevor Heslop is honest, decent and sensitive. Unfortunately, he works in a world of cutthroats and corruption, with nightmare clients and a rapacious partner with the morals of a barracuda. Add to that his dysfunctional family - estranged wife Meryl and teenage son Toby - and it’s a miracle he manages to stay afloat in the shark tank that is his life.

Stephen Fry and John Bird star in all four series of the BBC Radio 4 satirical comedy, plus the 2006 special episode. Set in the Machiavellian world of modern PR, Absolute Power introduces us to London-based 'government-media relations consultancy' Prentiss McCabe, whose partners Charles Prentiss and Martin McCabe are frequently embroiled in the machinations of the British political system.

Arch-Brutalist Sir Lucien founded his architectural practice on a commitment to brutalist concrete in all its forms. But fashion has been a cruel mistress, and four decades later things are not going well for Sir Lucien and his loyal(ish) employees. With no money and no commissions, times are tough – but it’s onwards and upwards (and upwards again) for the staff, as they go all out to win new contracts, deal with nightmare clients and fight to get their ambitious projects past the planners.

The second series of the award-winning sitcom written by and starring Morwenna Banks ( Absolutely) and Rebecca Front ( The Thick of It) set in, yes, a library, but no ordinary library. This is the library overseen and run by the most unlikely pairing since Mills met Boon. Meet Alice (Rebecca Front) - a former child prodigy who won a place at Oxford aged nine, but because Daddy went too she never needed to have any friends.

Norman is an idealistic, Beethoven-loving revolutionary. Max is a boring but cheerful timeshare salesman who won't stop talking. Fellow passengers on a flight to the Moon, they're thrown together to become reluctant companions after the lunar shuttle's toilet cubicle explodes, crash-landing them both on the desert sands of a distant alien planet. They are rescued by the friendly Oblivions, who could not be more delighted to see them. 

Two series of the BBC Radio 4 sitcom about an alien invasion of a small village, starring Hattie Morahan and Julian Rhind-Tutt with Peter Davison and Jan Francis. When the small Buckinghamshire village of Cresdon Green is invaded by an alien race called the Geonin, the local residents come up against Uljabaan, the smooth-talking leader of the aliens.

Inspired by Henry Cecil's 1955 comic novel of the same name, Brothers in Law first appeared on BBC One in 1962, providing Richard Briers with his first starring role on television as idealistic young barrister Roger Thursby. Adapted by Richard Waring from TV scripts by Frank Muir and Denis Norden, it took to the airwaves in 1970, running for three years until 1972. As the series opens, the rookie lawyer is in his first year at chambers, and struggling to learn the ropes. 

Here are all six episodes of the BBC Radio 4 sitcom written by and starring Ben Willbond and Justin Edwards about two incompetent science teachers who work at a college that specialises in drama, and whose world is turned upside down by the arrival of a new boss.
