A Steve Pemberton-scripted adaptation of EF Benson's arch novels of small-town social snobbery. Mapp And Lucia may seem to have comedy gold written all over it, but in truth this opener takes too long to get going and, for all everyone involved seems to be having fun, at moments lacks pace and zing. Things improve, however, once busybody Elizabeth Mapp (Miranda Richardson) and regal Emmeline Lucas, AKA Lucia (Anna Chancellor), begin to battle in earnest to lead Tilling society. Continues tomorrow and New Year's Eve.

Miranda Richardson interview

"I constantly want to give up acting, but I don't know what else I'd do."

Dead Boss comes to the end of its run and it's all change at the prison. Helen is moved to a new wing, where she finds a confidante in the shape of guest star Miranda Richardson. But creepy Christine makes every effort to maintain her friendship with her former cellmate, offering a unique take on bonding over arts and crafts: "Slasher bit the head off a sparrow and we're doing potato prints with its blood." Meanwhile the murder case becomes clearer - but only enough to allow for a second series.

A strong cast doesn't conceal the fact that, on the evidence of the opening two episodes, this new comedy scripted by Holly Walsh and the usually reliable Sharon Horgan (above) needs to be funnier and darker. Horgan plays Helen, wrongly sent to prison for killing her boss. Nobody on the outside, including her hopeless lawyer (Geoff McGivern), seems able to help, while inside she has to contend with the malevolent governor (Jennifer Saunders). Future episodes promise star appearances by Caroline Quentin and Miranda Richardson.

First shown last Christmas, this tremendous documentary tells the Blackadder story, describing the evolution of the main characters, not least Blackadder's transition from nerdy idiot to suave Elizabethan courtier. Tribute is paid to the vital contribution made by Miranda Richardson in her role as Queenie. Hugh Laurie acknowledges his high levels of stress. Then there are all the tensions that came from having so many creative people fighting their corner. "I remember it like a heart attack," Richard Curtis says.
