Gary, I'll echo what others have said: the film is one of the most faithful adaptations, very solid. The embellishments were primarily in the action sequences and some modernization. Now, I think it would be very cool if they were to make a Bond film now set in the '50's, but failing that, this one was good.
As long as we're talking, why did you drop the downside for psionics in the AD&D PHB? IIRC the supplement which introduced them carried a cost in spells if the character was a magic-user, strength if a fighter, etc., which balanced out the power of psionics.
And something else that's been on my mind for the last 25 years:
Keoghtom: 77 hp, 77% uniform magic resistance, 78 class levels
Murlynd: 135 hp, 35% uniform magic resistance, 36 class levels
Did you have some relation between these characteristics in mind when statting the quasi-deities, or did I just spend too much of my teenage years poring over Dragon? Heward doesn't fit the pattern, so it's probably just me, but thought I'd ask.
