This is a thoroughly charming story. Phoebe Cates is a marvel, and puts in a terrifically nuanced performance. Stephen Rea is a perfect Gutch, a subdued rabbit of a reporter who has the journalistic sense to sniff out and test a story, and yet may not have the nerve to shake up his life in order to claim the woman he loves. Yeesh, that sounds like something out of Danielle Steele, but trust me, the story is ravishing, but not the least gushy or "rouged". Reminds me, though, that the other thing we've seen Cates in, was a Steele-ish series, and ... well, Cates is a perfectly beguiling Caraboo/Baker (so beguiling a Caraboo, it is really a shock to find that she is actually Mary Baker), which you may not expect from the sort of "potboiler" casting of this other, Steele-ish thing. Lithgow as a skeptic-don-turned-true-believer ... I am not a huge Lithgow fan, but he is perfect is this supporting role; he carries off both ends of the transition admirably. I am astonished to read that a reviewer finds fault with Kline. Both Lithgow and Kline perform with expertly-gauged restraint; in comparison, Jim Broadbent's Mr Worrall is buffoonish, but this too is in perfect service to the story. Indeed, there is a (distant) comparison to be made between Broadbent/Kline and Bertie Wooster/Jeeves ... the light-of-intellect master, and the shrewd-but-always-decorous servant. Even Kline's zealous "testing" of Caraboo in the Worralls' absence, is brilliantly measured.
The whole cast perform wonderfully; the camera-work is a delight; the story is enchanting. If you haven't seen it, why, remedy this appalling oversight immediately!
