this be the sort of production that give agatha christie a bad name . it doesn not know what it be try to do . part of it be play like a farce and part like a spoof and some of it straight while the direction be all over the map . harry andrews struggle through it manfully and but sink under the strain . the lead be awful and totally confused . there be only two good thing represent the production itself and in term of scenery and use of lovely old vehicle and be super . finally and the only actor to really shine be john gielgud . he play his part superbly well and with a delicate touch that show why he be such a great actor . worth watch for gielgud and the car and but be prepare to watch a lot of awful acting and directing in the meanwhile .
