When I saw this movie at age 13 or so, I was terribly disappointed because it was clear that this is the third part in the story. Henry IV Part 1 and Part 2 come before this play, and they tell the story of Sir John Falstaff and his friendship with Prince Hal ( who is Henry V in this play.) The first two plays also introduce Nym, Bardolph, Pistol, and Mistress Quickly. Unfortunately, this play starts after Falstaff has been banished and Prince Hal has become King.
This play is a lot of fun, but it's very frustrating if you haven't read the earlier plays. There are so many poignant (or funny) moments that point backwards. Even the pretend audience at the beginning seems to feel that they want Falstaff back! The best acting moments in this movie are all scenes where the lower characters remember Falstaff and mourn his death.
Of course, there are some heroic battles and speeches in this movie, but looking back after forty years they don't seem as impressive as when I was 13. The great battle is actually over fairly quickly. And a lot of the later scenes drag, like when Captain Fluellen makes Pistol eat his leek. This is played as very bad slapstick when it's actually very violent and brutal in the play.
