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?

Peter Ustinov

Terence Alexander?

Another suggestion - Denholm Elliot. I think he wore a light coloured suit in Indiana Jones.

Sorry it's been said

This is frustrating because I can picture and hear a British character actor who would fit the bill but I haven't a clue what he was called and I can't remember anything he was in. Plump, posh, rather a high voice, babyfaced, wavy white hair, petulant. In loads of things on TV decades ago but never in starring roles.

Malcolm McDowell?

Has he been in Poirot op

Phillip Jackson

Roger Ashton- Griffiths

Rex Harrison?

Laurence Olivier?

Anton Rodgers

Roddy McDowel
David Niven

Have we had David Ryall? He’s the driving instructor in the Morse episode with Patrick Malahide?

I’m worried it’s going to be just a figment of op’s (dream) imagination! But some excellent guesses and trivia knowledge on here!

@Gasp0deTheW0nderD0g you saying 'petulant' reminded me of Dudley Sutton? Could it be him?

Not who I was thinking of, but might be OP's actor!

Albert Finney?

Martin Shaw?

I still think Denholm Elliott. I've mentioned him, and another couple of posters have mentioned him, but he isn't on your list. He was in A Room with a View, Indiana Jones, and, randomly I remember him in Brimstone and Treacle but that might be too obscure a reference.

Richard Bradford
John Stride
Barry Foster
Nigel Stock

Just checking it’s not Robbie Coltrane, couldn’t see him on the list.

Robert Hardy?

I agree with Joss Ackland

Robert Vaughn?

I was thinking of the guy from Lovejoy- Dudley Sutton - or Peter Vaughan
