Glengarry Glen Ross Old Vic, until 18 July Relics Lyric Hammersmith, until 18 July The Old Vic presents an eccentric new version of David Mamet’s ultra-masculine play, Glengarry Glen Ross. Director Patrick Marber populates the show with middle-aged actresses. And why not? Devotees of Mamet may find it patchy but the play is so powerful that it can survive any amount of experimental tinkering. The visuals are pretty incoherent and the Old Vic’s configuration gives the cast no help at all.
