Watching this vacuously flamboyant production by Calixto Bieito it's hard to realise Pedro Calderon's Life is a Dream stands as one of the greatest plays in European drama. Written in late 1620s Spain, it displays a rivet-ingly modern sensibility, with its idea of human consciousness wavering precariously between dream, illusion and reality. But Bieito's expressionistic production, played in a bare, black gravel wasteland over which hangs a huge, menacing mirror, is a triumph of creaky histrionics. It launches the theatre programme of Edinburgh's 1998 Festival with more of a whimper than a bang.
