He spent his early childhood in France and, owing to his family's travels, was never formally educated. Instead, he was schooled by governesses and tutors, and his education included tennis and ballet lessons. "In the beginning," his mother observed, "he had no homework. When he was older he had Spanish, German and music added to his studies. He read only selected books: English fairy stories, English and French classics; no crime stories. Having studied Peter for so long, I decided he was quite unfitted for any career except art, so I cut Latin, Algebra, high mathematics and substituted dramatics instead." Because of the widely varying national and religious backgrounds of his tutors, Lawford "attended various services in churches, cathedrals, synagogues and for some time was an usher in a Christian Science Sunday School...." Around 1930, aged seven, he made his acting debut in the English film Poor Old Bill.
