Sorry man, I personally see many differences there! Never get 'em confused!!
I think different people notice different sets of features. For example, I took a lot of drawing. People would look at 2
very different drawings done of the same model, same pose. Some would say "that first drawing looks
just like him!" while others would be like, "No it doesn't, the OTHER one does!".
Must be something like that...
Reeves' features are
much more thin, aquiline and delicate than Klein's.
Same for Wolf as opposed to Cruise. (In fact, I see no resemblance whatsoever between those two! I guess they both have brown hair . . .
)
