Who is the actor I'm thinking of...going mad

[Cantwait4weightloss]

You lot are good at this
I've googled, tried Chat Gpt all to no avail
He's British, blond, sort of curly hair and sounds posh
He's been in loads of things but never as the main character I don't think but he's instantly recognisable
I thought he was in One Day the film with Anne Hathaway but turns out no
He's the type of actor who is in Death in Paradise and stuff like that
I'm starting to wonder if I've just imagined him
It's doing my head in
He usually plays caddish sort of characters
Any ideas?
Sorry I've not provided much detail

Not James Norton
Not an angular face like his, more round

Owen Teale

Rupert Penry-Jones?

Samantha Bond.
Yes, I know she’s a she. And older. And red headed.
But I will never forget the thread where OP asked ‘Who is this actress’ - with similar description to what I have stated. And the thread went to nearly 40 pages with people getting exasperated, only for OP to declare…OMG ITS SAMANTHA BOND.
Someone had suggested Samantha fucking Bond on page 2 but OP had overlooked it. I vowed then to always suggest Samantha Bond, no matter what the description. Just staying true to myself. Love and peace.

Rafe Spall as well or Sam West (although, not sure he's Death in Paradise type)

Adam James

Jared Harris

Ben Miller

I thought Johnny Flynn but he’s not 50 I don’t think!

Another vote for Kris Marshall here

It would drive me nuts too OP, it’s like a song worm.

Tom Hollander

Rory Kinnear although he's a bit balding now.

Not Rupert but Chat Gpt was insistent that this was who I'm thinking of
Oh God I'm seriously worried about my brain now

Miles Jupp.

I bet it's Miles Jupp.

I've had an image come straight to mind, but I cant think of what he's been in either to see if I'm right 🤦♀️

Dan Stevens?

We’re all going maaad!

Like him but English
He's Aussie isn't he?

Not Dan

Adam James?

Commenting because I have to find out who this is 😂

I remember this and it was so frustrating 😂

Not Miles
I know who he is
He's not this mystery man!

JJ Fields?
