Help me identify this film from the John Lewis advert?

[BOFster]

It's driving me crazy

Here's a link to the John Lewis advert- take a look at the old movie showing on the television at 1 minute in, please.

Everybody thinks it's from It's A Wonderful Life, the embrace you can see at 3:21 in this clip:

But it really really isn't.

Oh Monty, you are the only one for me. The Penguin Imposter can sod off.

Maybe it cost them £1,000,000 to use the 3 second Pingu clip?

And the very best...

Veronica is very pretty...

You need Liz Taylor to keep him company BOF.

I'm out of ammo

Wouldn't surprise me Saga. I bet all the children's TV makers a squillionaires.

Before she was famous. How I love Marilyn.

Here she is

We can't have a thread glittered with Hollywood idols and starlets without Vivien Leigh.

Cary Grant aged beautifully didn't he?

I still want the ad agency or John Lewis to reply properly.

Liz and Viv are my favourites. It's the eyebrows.

And what is wrong with Veronica's eyebrows? Well, eyebrow. A damn fine one.

I can't stop googling pics now. She's so beautiful!

I still can't quite believe that clip IS fake....

It's a perfectly good eyebrow Arsenic but Liz and Viv pull off the look better than anyone whilst still looking stunningly gorgeous.

and Liz was doing the bold brow long long before today's teens.

Someone put up a gorgeous Hedy Lamarr. I'm on my phone now so I can't post pictures .

And maybe a young Marlon Brando?

Forgot pic. Yep, Liz beats them all.

There's a little part of me that doesn't quite believe it either, Arsenic.

Here you go

Dayum

Marlon with a kitty cat

Oh the look. Yes I see.

I can go to bed now I've seen Marlon

Good night
