The Madwoman of Chaillot (1969)

Film adaptation of the stage comedy. Nice, eccentric, idealistic and slightly mad Countess Aurelia, who believes that the good must prevail over evil, decides to stand up to corrupt powerful leaders of Paris by putting them on trial with 'unwashed masses' as the jury.

At 24:06, Gaston Palmer juggles 3 balls in the background at an outdoor cafe in Paris. He is seen in 6 shots over a 90 second period.

At 40:24, Palmer juggles 3 balls for Katherine Hepburn at another table in the same Paris cafe in 3 shots over 30 seconds. At one point he tosses a ball to Hepburn and she tosses it back for him to continue juggling. They do this several times.

Gaston Palmer filmed his scenes in 1968, at age 82, and died shortly after that, 9 months before this movie was released.
