Roland...of course.
But the other...and this might be controversial...Batman. I could so see Eastwood (at around 30 to 35) put on a Batsuit. The scowling mouth under the mask, his build, but mostly the voice. The best part would have been that he could have played opposite Jack Nicholson as the Joker back when he should have played the Joker instead of when he was old and chunky.
