A few, random thoughts:
It's a shame about the Sword of Truth series. I started reading the first book, got through about three chapters (which weren't bad), lost interest, lost the book (my cousin "borrowed" it, which is ok, because I turned around and "borrowed" his extensive collection of Magic: The Gathering cards.), and then heard that the rest was so much slop.
I stuck around longer (than I should have) for the Wheel of Time series. Here's some advice: just go read Dune.
I'm surprised noone mentioned the Riftwar saga. There's another series that started out really strong and then slowly but less-than-inevitably sunk like the Titanic.
Song of Ice and fire was great for the first two books. I kind of got lost by the third "let's scar/deform/ cripple/massacre/sideline all the characters" book, and have yet to return.
I just don't have enough hours in my day to fit in an ill-recommended, ill-concieved, ill-continued, or ill-fated series of books.
David Gemmel was great.
Sean Connery is not only too old, he's retired from acting. If you absolutely *need* an aging Scottish actor in your life, I suggest you start looking at Billy Connolly. He's amazingly talented.
For Druss, I'd suggest Vincent Regan, he played the Captain in 300.
If you could dry him out and clean him up, and if he could still do the physical training, Nick Nolte might make an amazing Druss. If you don't believe me, rent Farewell to the King sometime. It's not the best movie ever, but it's one of the best war-movies, and a movie that should be seen.
Ofcourse, I'm always up for the part
I'm a big guy, I'm aging badly, and I can handle an axe (I used to do a lot of land-scaping).
