I am looking to find more films which are derivative of "A Hard Day's Night" in either plot structure or theme, regardless of quality.

Essentially a film that takes a few people who are key of a style and/or fictional cultural movement and says "here we are, this is who we are and what we do" - they do not have to be entertainers, per se.

So far I have found

Spice World
Rude Boy
Penn & Teller Get Killed

Can anyone think of any others?

Don't forget about the guys whose entire career is derivative of "Hard Day's Night": The Monkees in "Head"

This is Spinal Tap.

KISS Meets the Phantom of the Park
Elvira, Mistress of the Dark
200 Motels(Frank Zappa and the Mothers of Invention)
Mrs. Brown, You've Got A Lovely Daughter(Herman's Hermits)

ABBA: The Movie?

I always saw the Monkeys, and "Head" itself, as being more derivative of "Help" myself.

Not what you're looking for, but it's interesting that TCM is running a marathon of early rock & roll movies tomorrow. I'd especially like to call your attention to It's Trad, Dad! at 3:30. It shares quite a bit of the style of A Hard Day's Night & must've been a big factor in getting Richard Lester that directing job. Cool scenes with Gene Vincent & The Temperance Seven among others...

It's funny this should get brought up because I've always thought of the Beatles movies as being derivative of the Marx Brothers movies.

Just not as funny.

Not to forget the Dave Clark Five in "Catch Us If You Can"

That Thing You Do!

The Monkees "HEAD"

IMO, far outdoes Hard Days Night as we ll as HELP

It actually has meaning to it and is pretty deep in its messages thru symbolism, etc. and stuuf going on in the world and the 60s at that time. Jack Nicholson was a co-write, btw.

I love it and wish it would get reissued with the extra 10 - 15 minutes of footage and OAR.
