Television: Today's Pick

One Foot in Broadcasting House (8pm BBC2) As part of the BBC's self-congratulatory 75th-birthday season, Patrick Wright, a Radio 3 programme presenter, guides us around that extraordinary BBC institution at the top of Regent Street. Designed by an inspired "nobody", one Lt Col Val Myer, and with decor by a brave new band of modernists, headed by Raymond McGrath (very little of which survives, alas), Broadcasting House soon had programme-makers up in arms over its technical and sound-proofing deficiencies, as well as acting as the inspiration for George Orwell's Ministry of Truth. Another controversy, involving the size of a certain part of the anatomy on Eric Gill's statue of Ariel on the front of the building, is finally addressed by the now 93-year-old actor who modelled for it.

Coronation Street (7.30pm ITV) Various long-running storylines climax tonight as pregnant crimper Fiona and hungover copper Alan (why, in soaps, do they always have their stag nights on the eve of weddings?) finally tie the knot. It's a toss-up as to which McDonald will stop the show - Steve ("you dun it wi' me dad, anya?"), Jim, busy nursing a bottle of whisky, or Liz, with her terrifying turquoise-and-white creation.

The film

A Cry in the Dark (9pm C5) Meryl Streep has never been what you might call a popular actress, with her technically impressive but often chilly performances. In Fred Schepisi's constantly intriguing 1988 recreation of the "Dingo Baby" case, Streep's love of a tricky new accent to master doesn't get in the way of a complex and uningratiating performance as Lindy Chamberlain, the Seventh Day Adventist who claimed that her baby was killed by a dingo at Ayers Rock. Sam Neill plays her husband.
