In the mid-80s, Thomas became involved with German author Heiner Müller, directing his works in the US and Brazil, and began a long-term partnership with American composer Philip Glass.

The blurb on the back cover was by Oscar Nominee and Golden Globe winner Fernanda Montenegro (and protagonist of Thomas's "The Flash and Crash Days") writes : "Gerald Thomas exists by virtue of his devastating quality, his inconstancy, his nonconformity, his aggressiveness, his faith laden disbelief, his life affirming death cult; through his clear and powerful incongruence; by laughing and crying like an innocent and somehow ominous child, by loving the neighbor he hates; by being an unexpectedly good, adorable boy and friend; by accepting and forswearing you in seconds; by loving you madly, by cursing you while blessing you; for his devilish, eternal and nonconformist Art is monstrously creative.

Cast: Maria de Lima, Lisa Giobbi, Julia Wilkins, Ana Gabi, Beatrice Sayd, Isabella Lemos, André Bortolanza, Ronaldo Zero, Wagner Pinto and Dora Leão.

In August 2003, Thomas directed a performance of Tristan und Isolde at the Teatro Municipal do Rio de Janeiro, the city's main opera house.

It was a nontraditional production in that the action was set in the office of Sigmund Freud—himself a character on stage, tossing cocaine in the air at one point—and made references to drug trafficking and violence in Rio.

[5] The following year, the Supreme Federal Court accepted and ruled on a petition for habeas corpus in favor of Thomas, granting it on 17 August 2004 and ordering the dismissal of the criminal case against him.

[4] Justice Mello, also voting in favor, argued that the established legal interpretation of Article 233 of the Penal Code required that the alleged lewd act should be sexual in nature.
