Comedians by TREVOR GRIFFITHS
This new play opened to rave notices at the Nottingham Play-house at the end of February. Trevor Griffiths, one of Britain's foremost new playwrights, has written an uncompromising play about what makes audiences laugh: set in an evening class in Manchester where Eddie Waters, a retired comedian, gives instruction in comic theory and practice. The play is concerned with the pupils' dilemma when they have to decide whether to follow Waters' altruistic teaching or aim for something more straightforward and obvious.

A series made specially for audiences in the BBC Regions and now seen countrywide.
The second of two films remembering the rigours and pleasures of life on the land. Not the years of today, but the years of half a century ago, when the horse pulled the plough, and the work-house brought cold comfort to the aged. Three people remember the West Country farm of 50 years ago, the sound of the plough, and the scent of a summer reaping.

Tony Bilbow previews two new American musicals.
The first, Funny Lady (a sequel to Funny Girl) stars Barbra Streisand recreating her 1968 Oscar-winning role. Her co-star, James Caan, narrates a filmed report on the making of Funny Lady.
The second, At Long Last Love, dedicated to the follies of the 1930s, has been created specifically for the screen by director Peter Bogdanovich, using Cole Porter songs and starring Burt Reynolds and Cybill Shepherd. Philip Jenkinson compares films actually made in the 1930s with Peter Bogdanovich's 70s version of the period.
