I watched "The Prince and the Pauper" (Warner Brothers, 1937) on a streaming service (I forget which one) yesterday.
It was a lot of fun, and Errol Flynn was just as dashing as ever, and the Mauch twins, Billy and Bobby, were also fun. Great cast of supporting characters, a massive production for its era. And it had the extra majesty of an Erich Wolgang Korngold score for that extra OOMPH.
It is due out next month on a Warner Archives Blu-ray disc. The streaming version was mighty fine, so it may have been that Blu-ray master that was used.
