Reminds me of that story about the casting of Patrick Stewart as Picard. Apparently Roddenberry originally had in mind a youthful, virogous figure much like William Shatner was for Kirk. So Stewart auditioned in a toupee to compensate for his baldness. An impressed Roddenberry realised that the toupee was pointless. Later when a reporter asked him why baldness hadn't been cured by the 24th Century, he said that society would be so advanced that no one would care anymore.
