I often think that when people in Britain complain about paying for the BBC licence fee, they overlook the fact that, like “I Claudius” and “Elizabeth R,” the network is capable of creating some truly exceptional drama for television or cinema. This initial installment portrays the beginning of the later years of King Henry IV’s (Jeremy Irons) reign, primarily through the experiences of his irresponsible son "Hal" (Tim Hiddleston), his companion "Poins" (David Dawson), and the perpetually drunk and cleverly opportunistic "Falstaff" (Simon Russell Beale). The monarch is contending with unrest from northern regions; “Hotspur” (Joe Armstrong) refuses to surrender the hostages taken during his recent victory over the Scots, holding them for ransom. This back-and-forth disagreement will force the Prince to abandon his drinking and demonstrate to his father and those who doubt him that he can step up and show himself worthy of inheriting the throne. Sir Richard Eyre has gathered a remarkable ensemble cast to present a narrative centered on rebellion, deception, and treachery, with Beale being particularly outstanding in his warm and energetic portrayal. Hiddleston also does a good job blending his character’s rebellious nature and indulgence as it gradually develops into something slightly more mature. Sir Richard has preserved much of the original dialogue's earthy humor and intensity, exemplified by Julie Walters’ brief appearances as innkeeper "Quickly" and Dawson’s playful “Poins.” It is dark, violent, filled with drinking, and realistically portrays a dangerous period in history. I am eagerly awaiting part two.
