Will Keen, in fine fettle in Shaw's funny but very flawed Man and Superman, also part of the Peter Hall Bath season, is in similarly sharp form in Moliere's Don Juan (translated by Simon Nye, writer of TV's Men Behaving Badly).

But oh, the difference of play and play. Don Juan which runs without an interval - clocks in at just half the length of the sprawling three-and-a-half hour Man and Superman. Brevity, as someone once remarked, is the soul of wit.

Nye's translation is demotic ('scam', 'posh'), low - perhaps unnecessarily so on occasion - easily-offended theatregoers be warned. The design, however- scenery is by Kevin Rigdon and lighting by Peter Mumford - is elegance itself.

Centre stage at the rear beneath three sides of a giant picture frame is a large mirror which becomes transparent as needed to reveal supernatural interventions, viz, the grim reaper himself and a statue which comes to life.

These arrive with a stern warning for Don Juan: mend your ways or face the consequences. For the Don is, in addition to being a hedonist, that most modern of things - a nihilist. He has no use for Church or the mores of man.

Thea Sharrock, who directed last year's excellent The Fight for Barbara, is in the directorial chair here and guides a fast-paced, punchy production. There are good supporting performances, especially from James Laurenson as Don Luis and Mark Hadfield as Sganarelle, Juan's much put-upon manservant.

Inevitably the sense of shock and scandal which greeted the play in which Moliere satirises society has long gone. Don Juan's final gambit, his announced intention to embrace hypocrisy and carry on sinning while castigating the morals of others passes for little, though it is this which finally tests divine patience too far leading to a very funny piece of physical theatre.

Keen isn't an obvious Lothario, more feral than fetching, but he is a fine vehicle for Moliere's unrelenting castigation of hubris, hypocrisy and fatuity.
