Hey, it's a small world and London is only part of it so anything is possible. Besides, watching Peter Morgan's screenplay unfold everything is wonderful. Brilliantly plotted, deconstructed and timeshifted in the style of, say. Pulp Fiction, Hamm views three emotionally-charged days from the differing angles of each of the titular protagonists built from the flashback perspective of practising psychiatrist Ray Winstone (an excellent and unlikely cameo).
The deadpan comedy is frequently laugh-out-loud funny with Sewell and Fiennes taking to it like ducks to water after their more serious roots. Hollander is unusually likeable, too, as the potentially irksome yuppie. But at the core of everything is newcomer Potter (previously glimpsed briefly as Nicolas Cage's wife in Con Air),bouncing elfishly from pillar to post, streetwise but confused, loved and loveable, and glowing like Julia Roberts circa Steel Magnolias.
Fun, feelgood and fast-moving — this is everything you wanted from a Brit romantic comedy (but were afraid to ask)
