Britain vs France

This idea is old. It dates back when all four actors were still alive. A series of movies starring 

Sean Connery (August 25, 1930) - Michael Caine (March 14, 1933)

Vs

Jean Paul Belmondo (April 9, 1933) - Alain Delon (November 8, 1935).

These actors became stars in 1960s where I love the period most. These actors would be gentleman thieves and master of disguise like Arsen Lupen. The movies would start in 1960s like the James Bond series. The competition between these duos will be gentlemanly without no clear winner. The French side will represent the continental Europe; the Britain will represent the Commonwealth countries and partially U.S.A.

There would be guest stars in each movie. I know French and Italian cinema better, therefore will mostly make suggestions for the continental Europe.

Belmondo and Delon would be accompanied by

Actresses: Isabelle Adjani, Nathalie Baye, Jane Birkin, Marie-France Pisier, Catherine Deneuve, Carla Gravina, Marlène Jobert, Anna Karina, Marie Laforêt, Romy Schneider, Mireille Darc, Marina Vlady, Claudia Cardinale, Marie Dubois, Mylène Demongeot, Brigitte Bardot, Sophia Loren, Stéphane Audran, Anouk Aimée, Monica Vitti, Annie Girardot, Jeanne Moreau, Simone Signoret, Giulietta Masina, Michèle Morgan, Danielle Darrieux, Marlene Dietrich and Arletty (ordered by age)
