The Olivier version is my favorite but Branagh makes a credible Harry. Branagh claimed that the film, Platoon, actually inspired his approach to the material. It's most obvious during the battle scenes. In terms of it's cultural impact it pales to Olivier's WWII rally; in fact, critics, at the time of its release, were of widely divergent opinions. I'm also not sure it has aged as well as the Olivier film, which is at least a deliberate tribute to the past. On the other hand, Branagh's contemporary take on a living, breathing 15th century England is impressive.
This is the only Branagh Shakespeare that I can stand.
And even this is a bissel fehrkakt.
Yes, it's my favorite by him as well. There are some brilliant touches interspersed, unfortunately, with long, moody pans. (I don't mind that sort of thing if it contributes to the narrative in some way. But "atmosphere" shooting always seems pointless.)
A bit of background on the Battle at Agincourt:
The final part of Henry V (the wooing of Henry's French cousin, Katherine) has never charmed me - probably because I've seldom seen it played right. Here are Robert Hardy as Henry and Judi Dench as Katherine giving it a go, circa 1960:
From the same Ages of Kings (?) series that includes the Daneman Richard III.
My favorite part of Olivier's Henry V (1944) is its first 15 minutes as Shakespeare's Globe theater is presented as it might have looked and the players as they may have played the introduction to the play.
. . . and my favorite part of the same film is when Henry and Katherine proceed to their thrones, then turn round and are the actors again, acknowledging the applause. (The expression on the boy-actor's face, the way his mouth is set, is particularly gratifying.)
Yes, I see what you mean. Quite a rousing finish, actually.
