The story follows British diplomat Justin Quayle (portrayed by Ralph Fiennes in one of his strongest and most moving performances to date) on a quest to find out who killed his beloved wife, an outspoken activist named Tessa (Rachel Weisz). The deception and conspiracy stretches much farther than he could ever have guessed, as he becomes entangled in a quagmire of intrigue involving major British pharmaceutical companies.
This intense film functions not only as a fantastic, on the edge of your seat thriller, but is an emotional and grief-ridden tale of love, death, and retribution. Although heavily criticized in the media for its wordy pretentiousness and erroneous liberal agenda, The Constant Gardener is, in my opinion, one of the best and most gripping human dramas in recent years.
The script, craftily penned by Steve Faber and Bob Fisher, works brilliantly as a comedy, but where the story really succeeds is in its poignant portrayal of human love and what that REALLY means. This is far more than just a "sex comedy," as it may appear on the exterior, rather a laugh a minute, but touching journey with some of the most likable, yet flawed, characters you're likely to meet.
