But did anyone else pick up a major Cyclops/Wolverine vibe between Guy Pearce's and Russell Crow's characters?

My impression came more from their interactions and their temperament, their clashing and their collaboration, and to some degree their look and manner.

p.s. apologies for this post not appearing in the movies section. 

I know the impression was somewhat superficial, but Exley's clean cut look (especially when he had issues being able to see without his glasses!), his cool strategist/tactician, contrasting with Bud's barely controlled rage, and how they came to have a begrudging respect for each other's approach, is what struck me. 

Interestingly Mark, I am surprised your take ignored who ultimately gets the girl :)

That's an interesting takeaway, Ron. Been several years since I've seen the movie. But Russell Crowe's character seemed to have his passions barely in check, while Guy Pearce's was more aloof and analytical. Their methods inevitably clashed when they worked together. And they were both  attracted to the same woman. 

Actually, the characters of Jack and Sawyer in LOST very much reminded me of the Scott/Logan dynamic. 

I plead ignorance to what has happened in the 40+ years since the Scott/Logan dynamic was first portrayed, save for the Fox movies (don't go there, please).
