Wow... Ok, Bogie fans, here's a unique treat for you -- a perfectly excellent noir detective story led by Robert Sacchi doing a holistic Humphrey Bogart impression so near-flawless that it's, paradoxically but truly and lovingly, a Bogie movie without Bogie. And a pretty darn good one at that.
Sacchi nails Bogart's look, voice, phrasing, facial expressions, posture, mannerisms, and cool suave. In fact, the only reason I said "near" flawless is that in some of the mannerisms he's too good. Meaning, he could have backed off a bit on the pointing, hand-to-lips, and face-twitch. He duplicates those Bogie quirks flawlessly, he just did them perhaps too often. Still, the performance is miraculous and only about .01% away from Flawless.
The wardrobe department nails the clothing (except for the paisley bathrobe... that one was a misfire). And the script captures not just the genuine hard-boiled spirit of Bogie's private dicks but also the emotional and ethical subtleties that Bogart displayed in most of his characters (with one exception -- a single line, an attempt at humor that was too lecherous for the character). Another smart feature of the script is its clever, un-forced nods to Hollywood history. But the dialog doesn't just re-use lines from actual Bogie films, it creates new quotables that are totally worthy of Humphrey Bogart's film legacy.
Other than the bathrobe, the theme song is the only truly bad thing about this movie (and it is genuinely atrocious!). But excusing those items and the photography in a few scenes looking like grade B 70s television production (modest budget), this is truly a great movie.
