'Thief' is one of the most underrated movies of the 1980s, if not of all time. Made in the early 80s by TV veteran Michael Mann, and co-produced by the future "king" of action blockbusters Jerry Bruckheimer, this movie can almost be seen as the transition from 1970s character based crime DRAMA to 1980s flashy but brainless 1980s crime ACTION. In that sense 'Thief' is the last great 1970s movie of the 1980s. Mann made at least two great movies after this ('Manhunter' and 'Heat'), but I still think it is is his best and most satisfying work. James Caan believes that the movie contains his finest performance and I'm inclined to agree with him. Caan is dynamite throughout. He oozes charisma and is impossible to take your eyes off, but also gives a subtle and complex performance. The film works both as an exciting caper movie, and as a human drama. In many ways it is the best crime film to pull that off since Dassin's 'Rififi' in the mid 1950s. Cann is helped by a superb supporting cast, who on the surface may seem a motley bunch, but all are very good - Tuesday Weld ('Who'll Stop The Rain'), Jim Belushi (his movie debut), a memorable cameo from country legend Willie Nelson, and especially a fantastic turn from Robert Prosky. Prosky is probably best known to most viewers as the kindly father-figure he played in 'Hill Street Blues'. His turn here as a ruthless gangster is a complete eye opener! Prosky delivers one of the most vicious lines ever heard in a movie, which is a bit too extreme for me to quote here, but believe me, you will never forget it when you hear it! Many people seem to find Tangerine Dream's dated synth score to be extremely irritating but I actually enjoyed it and thought it helped build the mood. 'Thief' is a hardboiled crime classic and is highly recommended to any fan of the genre, especially those made in the 1970s. It is wildly underrated and deserves to be rediscovered by a larger audience. 'Thief' is simply one of THE great "lost" classics of the last thirty years.
