I don't think there's any safe way of portraying drow so I don't know if a Drizzt movie would be possible.
- Cast black actors to play drow - Well no, you can't have a race of evil black people obviously.
- Cast white actors and use make-up - That's clearly going to be problematic.
- Cast racially diverse actors, don't use make-up but just use red or violet contact lenses to differentiate them from regular elves - This would be the best way of doing it but then you'd get the inevitable wave of D&D fanboys complaining that you'd strayed too far from the source material.
