One of the most powerful political thrillers of the 21st century is now available to stream on Amazon Prime Video.

Directed by Fernando Meirelles and based on the novel by John le Carré, this 2005 gem delivers a gripping and emotionally charged story of love, loss and corporate corruption - set against the backdrop of modern-day Africa.

The Constant Gardener follows British diplomat Justin Quayle, stationed in Kenya, whose wife Tessa is found dead under suspicious circumstances.

What begins as a personal tragedy quickly spirals into a complex investigation as Justin digs into Tessa’s unfinished work and uncovers a trail of corruption involving pharmaceutical companies testing experimental drugs on vulnerable African communities. As he retraces her steps, Justin becomes determined to expose the truth, no matter the cost.

Ralph Fiennes leads the cast as Justin, joined by Rachel Weisz playing Tessa. Supporting roles include Danny Huston as Sandy Woodrow, Hubert Koundé as Dr. Arnold Bluhm, and Bill Nighy as British government official Sir Bernard Pellegrin.

The film was directed by Brazilian Fernando Meirelles - who rose to prominence with the epic crime movie City of God in 2002 - and its screenplay was adapted by Jeffrey Caine from le Carré’s 2001 novel.

Shot on location across Kenya, the film blends dramatic storytelling with a documentary-like visual style. Meirelles made use of real locations - including Nairobi and the Kibera slum - and cast local people as extras in many scenes.

Author John le Carré has said the novel was based in part on real investigations into unethical drug testing practices in the Global South. The film’s release coincided with growing public awareness around the issue, contributing to debates on global health and corporate responsibility.

The film received widespread critical acclaim and multiple accolades following its release. Rachel Weisz won the Academy Award for Best Supporting Actress at the 78th Oscars, as well as the BAFTA Award and Screen Actors Guild Award for her performance.

It also received Academy Award nominations for Best Adapted Screenplay, Best Original Score by Alberto Iglesias, and Best Film Editing by Claire Simpson.

The Constant Gardener (2005) is now available for streaming on Amazon Prime.
