My suggestions for the remake(s)
One day, when I was bored, I came up with a list of possible actors to play roles in Discworld novels. Not entirely happy with all of them and some of the characters are missing an actor but here goes:
Rincewind: Gary Oldman, Eric Idle, Richard E Grant, Lee Evans, Kris Marshall (there is no way that Rincewind is the age of David Jason. I love him as an actor but totally wrong for Rincewind.)
Twoflower: Jackie Chan, Jet Li, David Yip
Trymon: Alan Rickman, Eddie Izzard
Death: Christopher Lee, Ian McKellen
Cohen:
Pretty Butterfly: Lucy Liu
Hrun: Orlando Bloom, Sam Worthington
Ridcully: Richard Griffiths
Ponder: Mark Addy
Granny Weatherwax: Sheila Hancock
Nanny Ogg: Miriam Margolyes
Magrat: Dakota Blue Richards
Agnes Nitt: Gabourey Sidibe (assuming she can sing)
Susan Sto Helit Emma Watson, Anna Friel
Albert: Pete Posthlewaite, Tom Courtenay
Brutha:
Verence: Dev Patel, Ewan McGregor
Vetinari: Tim Roth, Jeremy Irons, Jonathan Hyde
Vimes Gene Hunt, Tim Roth
Lady Sibyl: Pam Ferris would've been perfect but she's too old now
