I think some of the aspects of the Help script are timeless. The mad scientist:
"MIT wanted me, wanted me to rule the world for them." After the gun he's pointing at the Beatles fails: "British you see, useless. If I had a Luger, eh. Think of it, scientists properly equipped. The answer's with you, the voters."
The Scotland Yard inspecter is priceless too. In Buckingham Palace after George fans the cards: "What was that? It's haunted you know, this wing of the palace is haunted." And then George says: "What's that whirly thing comin' out of his stomach?" the inspector panics, covers his eyes "I daren't look."
The film is full of humorous lines and sight gags, it's a different deal from Hard Days Night, but classic Richard Lester comedy, silly, over the top, funny as hell.
In the restaurant, they order soup. The High Priest sharpening a big knive, glaring at them, "Soup, yes." continues sharpening the knife. John eating soup: "What are these, spectacles?" The easterner: "That's right sir, they're spectacles." John: "I think someone's been in this soup, what's this?" holding up a ticket. Ringo: "It's a season ticket." John: "I like a bit of seasoning in my soup." puts it back in.
I also love all the weird cars that get used thoughout the film. And the song clips are really some of the very first realized music videos, especially Ticket to Ride.
