Not sure about the formatting. Or the Max Bygraves catchphrase ....
SCENE 1. INT. SUBURBAN LIVING ROOM. 1956.
Father (side-parted and brylcreemed hair, waistcoat,
cigarette) and Mother (knitting) sit in a Nineteen
Fifties living room. Tommy Steele's hit song 'Rock
with the Caveman' blares out from upstairs.
TOMMY STEELE: (From Upstairs) "Rock with the caveman.
Roll with the caveman."
FATHER: That's the hundredth time she's played that
Rock'n'Rubbish record. I didn't fight Germans just
so's my daughter could send me back to the flippin'
Stone Age.
Mother replies as Father hurries out of the room.
MOTHER: Carole's having a bath. She's put her record
player on repeat play.
SCENE 2. INT. THE LANDING
TOMMY STEELE: (From bedroom) "Stalactite, stalagmite,
hold your baby very tight."
Father storms into his daughter's bedroom. But he
seems to be entering a Neanderthal camp.
DISSOLVE TO:
SCENE 3. EXT. NEANDERTHAL CAMP.
A group of Neanderthals (animal skins, painted faces,
etc) congregate around a dead fire. They are
frantically blowing the ashes and fanning with large
leaves to try to get the fire to burn again.
Desperation can be seen in their eyes. Father enters
the camp from a thicket. The Neanderthals all turn
round to examine him. A rather bemused father takes a
puff on his cigarette. The Neanderthals are amazed by
this mastery of fire. They prostrate themselves before
him. Father offers the Neanderthals' apparent Chief a
puff on his cigarette. The Chief ceremoniously takes
the cigarette, passes it to the Neanderthal Fire
Keeper who uses it to re-ignite the fire.
NEANDERTHALS: Uuurrhh! (Subtitled "Fire!")
SCENE 4. INT. NEANDERTHAL CAVE. (MONTAGE)
Father is ensconced in a cave. A choice of nubile
Neanderthal girls is offered to him.
SCENE 5. EXT. NEANDERTHAL CAMP. (MONTAGE)
Cold winter. Father has fur skins over his fifties
clothing. The Neanderthals have now greased their hair
into a side parting like Father's. They have made a
Snowman. Neanderthal children play around it.
SCENE 6. INT. NEANDERTHAL CAVE. (MONTAGE)
Father is ensconced in his cave. It has three flying
duck-like birds painted on the wall.
SCENE 7. EXT. NEANDERTHAL CAMP. (MONTAGE)
Hot summer. Father, now with longer hair, has rolled
up trousers, braces and a knotted handkerchief on his
head. The Neanderthals have imitated him with knotted
leaves on their heads and rolled-up skins covering
their legs. Neanderthal children play - two smaller
children have much fairer hair than the others.
SCENE 8. EXT. NEANDERTHAL CAMP.
The Communal fire burns. Neanderthals are
unsuccessfully rubbing sticks together to try and
create fire. Father now has long hair.
FATHER: Come on, you perishers. You need to be able to
create your own ruddy fire.
SCENE 9. EXT. NEANDERTHAL CAMP. (MONTAGE)
The children play. One fair-haired child kneels behind
a Neanderthal child while the other fair-headed child
pushes them over.
SCENE 10. EXT. NEANDERTHAL CAMP.
The Neanderthals play an improvised game of cricket
with bones and coconuts. The Neanderthal bowler makes
an exaggerated appeal.
NEANDERTHAL: Uhl! Beee! Wurr! (Subtitled "LBW!")
SCENE 11. EXT. NEANDERTHAL CAMP.
Neanderthals demonstrate a new mastery of fire -
lighting small fires by rubbing sticks together.
There's joyous celebration. The chief shouts to Father
at the edge of the camp.
NEANDERTHAL CHIEF: A good idea (beat) son. (subtitled "A
good idea - son.")
Unobserved, Father leaves the camp by the thicket; he
seems to be entering the bedroom.
DISSOLVE TO:
SCENE12. INT BEDROOM.
TOMMY STEELE: (From Record Player) "Shake with the
Caveman."
Father's looks like he did originally. He stares at
the Dansette record player. The arm is retracted for
repeat play; a 78rpm disk plays. He lifts the needle;
the music stops.
SCENE 13. INT LIVING ROOM.
Father enters. Mother looks up from her knitting.
MOTHER: You need a haircut, Pa.
Father looks distracted.
FATHER: You know, Ma, I think I just might be the
Missing Link.
