to take the whole Bond franchise into a more alternative yet still the same charming ladies man vibe
James Marsters
find him a very talented actor (definitely one who can sell a role well), first as Spike in the Buffyverse, where he also was quite the charmer around the ladies
and more recently in Marvel's Runaways as Victor Stein where he showcased himself more as a genius professor
but yeah my main choice would be Idris, but James would be a good second choice of mine
