I can't explain even to this day why someone who was around 11-12 (me) found Reese Bennett such a facinating character. I collected the comics and I watched the show, and I wrote my own stories revolving round him. Neville Brand was just so cool, as far as I was concerned. I don't know how to explain it.
I guess I've always been the odd one-- Reese Bennett, Illya Kuryakin, Artemus Gordon, Manolito Montoya-- I've always been a fan of the "side kick", or the anti-hero type!
And as someone once told me, being the "character actor" is really cool-- you get to do so much, and it's more meaningful when someone really appreciates your work!
