My dream team for a film version
If they made a big screen action version of this and did it in a style that the recent Tinker Tailor Soldier Spy remake did it- ie; update it but make it big-screen cinematic and modern reaching but still set in the 70s tone then I'd love to see it happen.
The big screen version could be still called The Professionals or perhaps CI5,
Daniel Craig as Doyle, Jason Isaacs as Bodie and Gary Oldman as Cowley.
That would be AMAZING casting.
Throw in talent like Ralph Fiennes, Liam Neeson and Michael Caine too as bad guys/ asscoaites.
That would be my dream team but if they cast younger (than Isaacs and Craig-both in their 40s) then I would go for Ben Whishaw as Doyle and Tom Hardy as Bodie keeping Oldman as Cowley.
They should do this.
