Jane and I were contemporaries. Born the same year in 1946. Me in February, she in December. We had the same kind of upbringing too – her mother was an actress, mine an artist, and we both had military fathers. And we were just pretty girls living in London in the 60s with all those 60s changes flooding in, the 60s dream, being spotted and brought into films, enjoying free love and all the new ideas for our creative expression. We were suddenly so much freer than our parents who were just bemused by it all. But there was no stopping us, the world was ours for those few years.

According to Charlotte Rampling, left, whatever Birkin did, she put herself fully in the role, making it different, special, unusual.

Our first film was the same one, Richard Lester’s The Knack… and How to Get It (1965). We had a scene standing on the stairs together, but we just sort of bumped into each other there – no friendship then as such. I identified with Jane more after we had both landed in France, me much later than her, after I married [in 1978, to her second husband, musician Jean-Michel Jarre].
