Help me remember the actor's name

[PGmicstand]

Just to satisfy my itching brain!
Had a dream last night which featured an actor walking across a car park. He seemed familiar and I'm sure he's a real person.
The problem is, I can't think of much detail.
He's the sort of person who'd be in drama things like murder mysteries or maybe period dramas of the 1920s/1930s - he'd be playing a hotel proprietor type character.
I think he's fairly tall. He's an older actor - or at least, was then - he may have died.
White hair, with a bit of a wave, sometimes worn slicked back. A bit 'jowly' but not with a particularly wide face and has a moustache.
It's NOT Richard Griffiths. There's a similarity but the actor I'm thinking of has a narrower face than that and I don't think he has glasses.

Any ideas?

Denholm Elliot

Richard? Robert? It's ROGER Allam. Never was a man more of a Roger.

No.
James mason is too handsome in comparison. Donald Sinden has too high a hairline. Michael Horden has too large/prominent a nose.

Unfortunately not. I don't think this is someone as well known/famous.

No, not that lovely boy.

I think he was already suggested but no.

Joss Ackland?

In every sense. Mea culpa, mea maxima culpa.

No. Kenneth's eyes are much more eye-baggy than whoever it is I'm trying to recall.

It sounds like him.

Jumping on this thread i thought i saw someone famous in London but can't put my finger on their name. Looks similar to Ben Kingsley but younger probably 50s

a few suggestions
david warner
Terrence hardiman
John woodvine
kenny ireland
Phillip jackson
Simon beale
Peter vaughn
david ryall

My biggest fear at the moment is that this will not be resolved!

Tom Conti or Nicholas Le Prevost? I like Simon Beale as a possibility too…but he is quite short.

Wikipedia actually has a page that lists British actors by the decade of their birth. Might be worth a wee scroll through that if you think that the name will jump out at you when you see it!

From there….Rupert Vansittart? Quite jowly!

I've gone through all the suggestions so far.
Still the closest in appearance are Richard Griffiths and Peter Ustinov as Poirot but not quite either of those.
Richard Griffiths' face is too wide, Peter Ustinov's isn't long enough.
I wish I could do some sort of photofit. I can see this person clearly in my mind's eye.
So frustrating.

Here's the list with comments, so you can all keep up.

Frank Middlemass?

I'm with @MamaBobo . If this isn't resolved today there are going to be so many MNetters still awake at 3am scratching our heads.

Robert Morley?
Albert Finney?

Or Donald Pleasance

Hywel Bennett?
Keith Baron?

Leo McKern?

Peter Ustinov?

I reckon this is a very good guess.

It’s all gone a bit Father Hank Tree. Father Hiroshima Twinkie. Father Stig Bubblecard. Father Johnny Helzapoppin. Father Luke Duke. Father Billy Furley. Father Chewy Louie. Father John Hoop. Father Harry Cakelinem. Father Rabulah Conundrum. Father Pee-wee Stairmaster. Father Tri-Peglips. Father Jemimah Ractoole. Father Jerry Twig. Father Spodo Komodo. Father Canabramalamer. Father Todd Unctious.

Peter Jeffrey?

Ciaran Hinds?
