Duncan Jones's 'Whistle' tells an amusing little tale of a hit-man using ultra high-tech to complete his missions. The plot may appear a little contrived (it's only thirty minutes long) but it still manages to engage and entertain. The main concept is barely original but the idea of using high-tech and I thought the cold relationship between the husband and wife was interesting as it sort of adds up in the end. The acting is adequate. Jones's special effects are minimal but effective nonetheless. The gadgets and gizmos look very real. Jones also seems to know how to use music in a film because the soundtrack here is outstanding. With his first film, he already shows a lot of promise and, last year, with his first major feature film, Jones proves that he's here to stay.
