An exceptional speech makes you speechless and leads you to his world unconditionally.
This is the one: the final cut of a movie called the Great Dictator directed and acted by Charles Chaplin in 1940 was used in a commecial clip in Japan.
The moment I watched it, it was a commerial short movie and I got freezed and couldn't skip this on Youtube. The conbination of the level of his tone, volume and his quality voice were perfect for me. It was too easy to understand that most say this speech is the best.
このCMのスピーチ、最初に見たとき、言葉にできない、表現できない感情と共に心に衝撃が走りました。言葉の力強さ、その意味と重みが言葉のトーンにバッチリはまってるような、声だけでもってかれたような感じでした。
ヒトラーをチャールズ・チャップリンが演じた映画、「独裁者」の中のラストシーン。このCMは抜粋してますが、本編は６分間で史上最高のスピーチと言われています。
全編はyoutubeにあります。日本語訳も検索すればあります。是非！
