On paper it's hard to understand why the 1937 version of The Prince and the Pauper isn't better remembered today - lavishly filmed by Warner Bros. at their peak with Errol Flynn, Claude Rains and Alan Hale starring, Erich Wolfgang Korngold scoring and Sol Polito lighting for their Robin Hood co-director William Keighley (with help from an uncredited William Dieterle when he fell ill) with a literate and witty script and a real pair of identical twins (Billy and Bobby Mauch) who can act as well as the script demands, it should be an absolute winner but instead has to settle for entertaining but a little disappointing considering the talent involved. Part of the problem seems to be that 'lyrical' pacing that got Keighley replaced by Michael Curtiz on the Sherwood Forest gig - he's so in love with the scenes in the palace that the film's nearly half over before the Prince suddenly finds himself a Pauper and Errol Flynn enters the fray as his impoverished but stylish accidental protector. Indeed, despite his top-billing, Flynn's a minor supporting player here, all but disappearing from the film's finale as things threaten to draw to a standstill with what must be the longest coronation scene in screen history - nearly two reels, apparently designed to cash-in on the massive international publicity surrounding King George IV of Great Britain's coronation the week after the film opened.
At times the film feels both over-written - albeit entertainingly so, with some elegant verbal barbs - and under-plotted, lingering so long in court with the long time a-dyin' Henry VIII (Montagu Love) that it has to race through much of the Prince's rude awakening to life in the kingdom his double has inherited. Yet if it wastes its star for much of its running time, there's some choice-cut villainy from Claude Rains' would-be Lord Protector and Alan Hale's villainous Captain of the Palace Guard, here Flynn's enemy rather than his sidekick, and there are some interesting political machinations and a rare emphasis on the religious divisions of the time. It may be a couple of rewrites and some tighter editing away from a classic, but it's still one of the more entertaining versions of Twain's tale and works well enough for most of its two hours.
A word of warning - try to find Warner Home Video's Region 1 NTSC transfer, which boasts fine print quality and the original theatrical trailer, or their French PAL release (available from Amazon.fr as Le Prince et le Pauvre) rather than Cornerstone's dubious Public Domain release which has a typically poor standards conversion transfer.
