Annie! I'm back and I'm raring to go! (see I'm even writing in limerick metre...)

In reverse order:

Roger -- Planet of the Apes
Jayne -- 39 Steps (The guessing bit is fun! But I want others to join in!)
Annie -- L'Année dernière à Marienbad
Roger -- 6th Sense/Cool Hand Luke
Annie -- The Virgin Spring and...I'm stumped on the ménage à trois

Phew...

(Now I must go. At work on a staffroom computer! ;))

Ah, the ménage à trois was Jules et Jim. Did you get No.27?

Johnny Guitar!

(had to do some sleuthing though)

A simian, fearsome and great,
Fell in love with a girl, but his fate
Wasn't happy, alas,
Since it soon came to pass
That he fell from the Empire State.

If you steal and then check in that's why
you may have to shower and die
You've made mother jealous
although she will tell us
she's harmless, and won't hurt a fly.

Kong!

Psycho!xxx

A nanny who’s awfully jolly
(but what you might call “off her trolley”)
indulges in pranks
which amuse Mr Banks.
She flies off - as she came - with her brolly.

A teenager took as his bride
A girl, but he then had to hide
The marriage because
He had rotten in-laws,
And then, to be brief, they both died.

A man on a bridge, so forlorn,
Convinced that nobody would mourn
If he jumped, was then shown
What he ought to have known:
Things were better because he'd been born.
