But there's no reasoning with the mentally insane. 但跟精神病人根本没道理可讲。
Generally characters that are deeply depressed, mentally insane, or who go through big dramatic changes in their lives are the hardest to dub. 凡是来讲,情绪万分低沉、精力变态或履历了人山口胜平配过的角色的生活伟大变故的脚色是最难配合制造的。
To become mentally deranged or obsessed; go insane. 变得精神错乱(MI)或迷乱;发狂。
