Anton Blake Horowitz embarked on his artistic journey as an intern at the Space Theatre in South Africa, a groundbreaking performance venue that fostered diversity and defiance against the Apartheid regime. Shortly after, he relocated to the UK, where he honed his craft at the prestigious Drama Centre in London. Following his graduation, Horowitz founded his own theatre company, showcasing his versatility by performing in a wide range of classical and contemporary plays across the country and in Berlin.
In 1989, he made his debut in Robert Chessley's two-character play, Jerker, which explored the poignant relationship between two gay men amidst the AIDS epidemic, under the direction of Stephen Daldry, then the artistic director of the Gate Theatre. The following year, Horowitz returned to his country of exile, where he continued to thrive in various mediums, including theatre, opera, and television. He notably appeared in the role of Mick in the Caretaker, the first Harold Pinter play to be performed in South Africa since the cultural boycott, and as a White Supremacist assassin in the local series, Game II.
Horowitz spent several years in the US, primarily in New York, where he acted in a variety of theatre productions. He eventually returned to the UK to work at the National Theatre Studio. In the past decade, he has been active in several BBC and ITV productions, as well as international films. In addition to his acting career, Horowitz has also made appearances in commercials and voice-overs across various countries. Furthermore, he holds a Master's degree in Screenwriting from Royal Holloway, University of London, demonstrating his multifaceted talents.
