More easy than hard. Thank God!
Of course, I should plop an asterik in there to qualify that -- It's easy* IF I've spent enough time (and had enough good fortune) to learn about and get to know my characters. Oh, and it helps a ton if I can "see" them in my mind's eye. If I haven't, and if I can't, then "easy" gets tossed out the window.
Dialogue is FUN for me. I cannot lie, though. Breaking story -- and that wacky, heart-pounding, inspirational rush that comes with it -- is the most fun about screenwriting for me. Crafting dialogue that uniquely and correctly suits my characters lags behind in a mid-distant second. But it's still fun.
And just because I claim it's more easy than hard doesn't mean crafting dialogue isn't work. It is! It takes time .. and commitment .. to hang in there and toy and toil and muddle and muscle around with characters until their dialogue surfaces.
But it's worth it! And therein lies the FUN.
