According to Hyoe ENOKI, an excellent supporting actor who had often appeared in Nakahira's films because of his performance laying his life on the line and his unique appearance, for example, the part of a killer who did a desperate stunt to become a fireball with gasoline in "Wakakute Warukute Sugoi Koitsura" (Young, evil, and excellent gays), Nakahira, who had been a dandy as a stylist since he was an assistant director, had a long face and got really mad when he was called a 'horse face' by Yasushi SUZUKI and Hyoe ENOKI at the time of shooting of "Yaro ni Kokkyo wa nai."
『若くて悪くて凄いこいつら』の殺し屋役で、ガソリンを浴びて火だるまになる決死のスタントを自ら行う等、その体を張った演技と特異な風貌で中平にも度々起用されていた名バイプレーヤー・榎木兵衛の話によると、助監督時代からスタイリストとしてダンディーな中平であったが、面長な顔だったため、『野郎に国境はない』の時に鈴木ヤスシと榎木兵衛から「馬ヅラ」と言われて本気で怒ったそうである。
