'Raising Steam' Casting

[Richard A Thackeray]

I'm re-reading the titular Pratchett book again, & was idly thinking of who could play the major roles
https://en.wikipedia.org/wiki/Raising_Steam

Any ideas, gentle readers??

Moist von Lipwig & Adora Belle are already perfectly cast, from the 2-part TV film 'Going Postal

As are Drumknott & Lord Vetinari (prefer Charles Dance, personally), Sacharissa Cripslock & Sergeant Angua


So, mainly, who would play Harry King & Dick Simnel?

If, we could transport deceased actors, I'd think of Peter Vaughan (rather spendidly, also a Harry, as 'Grouty' in Porridge)
From today, maybe Ray Winston?

Dick?
If anyone saw the recent 'Biggest Little Railway' 5-parter, with Dick Strawbridge (& the lovely Claire Barratt), there was a young lad as part of the team.... .Callum???
Not the H&S obsessed lad, with the glasses

He was, purportedly, 18
His father had died, but his mother had taken him to various steam events, & he'd built his own working steam locomotives, & traction engines
Perfect!!!!


Then there's;
Nobby (Tony Robinson, in full Baldrick persona??)
Colon

The Low King (Rhys Rhysson)
Ardent
