of the West," Quast has said. "In fact, there is very little material to work with in the script. Trevor would say things in passing like 'Have you read the Ten Commandments recently?' That's all he would say. If you're thirsty enough, you can follow it up ... there was the whole basis of our legal system and the explanation for the whole of Les Mis. For me, that's inspired directing. That's why he's such an awesome man." When playing Javert, Quast gained a reputation as a perfectionist. He also began experiencing intense bouts of stagefright. "I had a terrible time," he said. "It took me a month to get over it. At one stage I wasn't sleeping at all but lying awake planning speeches to the audience about being sorry and could I start again." 1990s Quast's stage success continued as he won the coveted role of Georges Seurat in the original London production of Stephen Sondheim's Sunday in the Park with George for the Royal National Theatre. In 1991 he won his first Laurence Olivier Award for Best Actor in a Musical as Georges Seurat and George. Quast was under a large amount of stress when preparing for Sunday in the Park with George, as he struggled to master Sondheim's complicated musical scores (Sondheim told him: "you don't play tennis against people you can beat."), learn to paint and sketch for the play, and waited for the impending birth of his first son, who was due five days after opening night. In 1993 he returned to Australia to play in Sydney Theatre Company productions of William Shakespeare's Coriolanus and Sondheim's Into the Woods, in which he played The Wolf/Cinderella's Prince. He then played Dunois in Bernard Shaw's Saint Joan in the West End and on a UK tour in 1994. In 1994–96 he spent two seasons with the Royal Shakespeare Company, performing as Fred/Chorus in A Christmas Carol, and King of Navarre in Shakespeare's Love's Labour's Lost, as well as Lodovico in The White Devil, Banquo in Macbeth, and Achilles in Troilus and Cressida. Before returning for a second season with the RSC, he spent some time back in Australia, performing in the national tour of The Secret Garden as Dr. Neville Craven – along with Anthony Warlow and Marina Prior. 2000s Musical theatre Quast played the part of Javert on the Les Misérables Complete Symphonic Recording, and
