In a world where the computer-fuelled excesses of screen and multi-media put the humbler resources of live theatre in mortal danger, The Right Size remind us that you can't beat the simpler powers of human imagination and sheer bloody charisma.

Sofa nightmares: Foley, Jones and McColl in Bewilderness

The utterly engaging duo of Hamish McColl and Sean Foley can take the Oxford Playhouse audience on a fairytale white knuckle ride without a microchip in sight. Part comedy stand-up, part circus act, part surreal performance art, their latest offering whisks you through a manic adventure set, as all the best ripping yarns are, down the back of a sofa.

A plot summary? It seems a travesty to attempt one, since one of the many joys of Bewilderness is the feeling that you never know where you are going next. The gist is that two men, Terry and Maurice, dressed in brown paper suits arrive at a cottage for a golfing weekend but are cast into a parallel world when they climb down a sofa to answer a cry for help from an old man stuck down there since childhood.

There follows a deliciously daft, if occasionally uneven, romp in which our heroes attempt to escape their nightmare and, in doing so, learn a little (though not too much) about life. Hardly any theatrical device is left unexplored, ranging from a spectacular, cinematic escape attempt to the pyramids, to some rather impressive magic tricks. Oh, and loads of top draw one liners.

The duo are joined in this show by two collaborators. One is the excellent Chris Larner, a ringer for a young Kenneth Baker in pinstripes and glasses, who hovers throughout like a menacing butler, bashing out sparkling ditties on his banjo and ending up - in a moment of high surreal art - as a giant blue brush.

The other is Charlbury's own Freddie Jones as the old man. He provides an amiably shambling contrast to the frantic mayhem, but too often his arrival heralds a swift collapse of energy levels and comic momentum - a problem which more performances might iron out.

Yet Bewilderness offers an unbeatable way of spending 80 minutes of your life - all the more enchanting for its rough edges and raw cheek.

And, in the words of the song lobbed recited by the old man, a healthy reminder that in good art "the fundamental things apply".

**Bewilderness runs at the Playhouse until tomorrow.
