They gave us Jon Hamm and Daniel Radcliffe sharing a bath in A Young Doctor's Notebook and now we've got Kylie Minogue gyrating to The Velvet Underground - Sky Arts' Playhouse Presents... certainly has pulling power.

In Hey Diddly Dee, a star-studded cast - Mathew Horne, Peter Serafinowicz, Homeland's David Harewood sporting a Brummie accent - find themselves caught up in a theatrical black comedy which trips them back to Andy Warhol's Factory glory days, with a potentially fatal clash of ego and ambition.

Oh, and a scene-stealing black cat.

The second series of this comedy about a hopeless salesman (played by co-creator David Cross), has been hanging around for two years before finding a home on FOX. It's nowhere near as good as its excellent line-up of stars.

The superb Will Arnett (from 30 Rock) makes a brief appearance and Sharon Horgan is woefully under-used. Mad Men's Jon Hamm also turns up in a cameo role. It's very chaotic and silly, and contains some ill-advised rape "gags" that should never have reached the screen.

The young doctor's morphine addiction has a deadly grip: hollow-eyed, working at that terrible clinic in the middle of nowhere, he is abject. Meanwhile, his older self (Jon Hamm) too is unhappy: when the pair "meet", they fight. Though there is a scene that will delight Hamm and Daniel Radcliffe fans when they share a bath.

It's the final episode, so there's a sense of an ending for both. The young doctor is called out in a blizzard to a woman with a serious head injury. His "treatment" is shocking, but he's detached - it's the morphine. When he tries to resist, his world spins.

This comedy drama has delivered record-breaking ratings for Sky Arts, hopefully as a result of its excellence as an adaptation of Mikhail Bulgakov's short stories as well as the celebrity of Daniel Radcliffe and Jon Hamm, both also superb. In tonight's final episode, the Doctor's morphine addiction, an inevitable response to a snowbound life in which every knock at the door brings a fresh hell, becomes overwhelming. The series' triumphant tragi-hilarious balance is particularly well struck in the incident of the husband with the dazzling trousers.

The older doctor (Jon Hamm) is in the sweaty grip of his morphine addiction as these slight tales at last take on some substance. Back in that frosty clinic decades earlier we see the start of his reliance on the drug, as the young doctor (Daniel Radcliffe) is driven to distraction by a toxic mixture of claustrophobia, boredom and fear. Only an armful of morphine can set him free.

A young girl is brought in, dying from diphtheria; her mother is hysterical while her aged babushka is in such a frenzy that only a shot of formaldehyde will shut her up.

The older doctor (Jon Hamm) is looking sweaty and wan in his 1934 Moscow practice under the withering gaze of a Soviet soldier. As they both stare meaningfully at his diaries, we are wafted back to 1917 and that spartan clinic in the back of beyond.

On the page this is one of author Mikhail Bulgakov's most poignant stories, as the young doctor (Daniel Radcliffe), who has grown a feeble beard in the hope that it will make him seem more mature, faces a terrible predicament when a distraught father brings in his gravely injured young daughter.

Prepare for buckets of stomach-churning gore (be warned, it's unsparing) and low farce.

Adapted from Mikhail Bulgakov's series of short stories, Sky Arts 1's four-parter was always going to be darkly comic. But it's not until Daniel Radcliffe, playing a callow backwoods doctor at the dawn of the Russian revolution, amputates an eight-year-old girl's leg that the humour in this second episode really kicks into high gear (if you'll forgive the pun). Fine, Sky's PR team can call this a 'comedy drama' if it likes. But this is gross-out slapstick of the highest order - having more in common with The Evil Dead than any brooding, costumed piece of period schmaltz. Meanwhile, the noose continues to tighten round Jon Hamm, who plays the older version of Radcliffe (the show is essentially a series of flashbacks, in which the older doctor counsels his younger self). Will his state inquisitor discover he's addicted morphine? Almost certainly, but it's difficult to care when the set pieces are this brilliant. Comedy, 1. Drama, 0.

Sky's been on a bit of a role in terms of comedy commissions. While most of the notable ones have been on Sky1 and Sky Atlantic, other channels have been making their own shows, with this one coming from Sky Arts 1.

A Young Doctor's Notebook is based on a collection of short stories made by the Soviet novelist Mikhail Bulgakov, most famous for his book The Master and Margarita. The story's told via extracts from an old doctor in 1930s Moscow (played by Mad Men star Jon Hamm), about his experiences working in tiny village hospital in the middle of nowhere just after his graduation in 1917 (his younger self being played by Daniel Radcliffe of Harry Potter fame).

The opening story see the young doctor arrive at his new practice and dealing with his much more experience staff: Anna (Vicki Pepperdine), a midwife who is obsessed with the doctor's late predecessor Leopold Leopoldovich; fellow midwife Pelageya (Rosie Cavaliero) and the boring feldsher (Adam Godley). As the story goes on, the young doctor finds himself mysteriously in conflict with his older self, who keeps telling him what to do.

This opening episode was highly enjoyable. I've read some of Bulgakov's work before (i.e. Heart of a Dog) so I know a bit about his life and the book's in some ways based on his own experiences as a doctor in the Russian countryside. It does make you wonder exactly how much of it's based on stuff which occurred to him as there's quite a lot of gore. One of the most horrific yet funny scenes involves the young doctor trying to extract a tooth from a patient, which first leads him to drag the patient around the floor, before doing something I don't think it would be wise to mention now.

It's not just the slapstick which is good, but the characters too, especially the staff the doctor has to work with. The feldsher for example makes a study of how many things you can possibly fit into the young doctor's luggage (he counts socks individually).

Many people will be watching A Young Doctor's Notebook just to see the high-profile leads, but there's much more to this programme than just the cast.
