When visiting Scotland I got into Rebus. Happily, Warren is a bit of a fan, too, collecting those that have been televised or turned into movies.
Detective Inspector John Rebus is the protagonist in the Inspector Rebus series of detective novels by the Scottish writer Ian Rankin, ten of which have so far been televised as Rebus. The novels are mostly set in and around Edinburgh. …
Rebus can be said to belong to a long tradition of paternal Scottish hard men. A natural leader whose gruff exterior and fierce will to succeed in his field belies a benevolent nature. …
In the Rebus television adaptations he was played by John Hannah in the first two series, but in the later series the role was taken over by Ken Stott to much acclaim. …
Hannah is a terrific actor, but I’d say Stott is much truer to the Rebus of the novels.
Leave a comment if you’ve an opinion on the two actors.

I’m addicted to the Rebus books and dreading reading the last one, which will happen very soon, but have never seen any of the film versions. Based solely on the Google images of the two actors in their roles as John Rebus, I have to say that Ken Stott looks perfect for the role. (Before I knew about those two actors, I was thinking maybe Gerard Butler would make a good Rebus, but I’m not sure that he looks world-weary enough.)
