Actors who had sizzling onscreen chemistry, but for some reason never made another movie together.
John Wayne and Eiko Ando (The Barbarian And The Geisha) - Not only did they never appear in another film, this was also Eiko's only acting role. But they were so natural together you'd almost think they were dating behind-the-scenes.

James Stewart and Dean Martin (Bandolero!) - Stewart and Dean are a lot of fun to watch playing each other off as brothers. Every dialogue exchange is a blast, and this is the kind of chemistry between actors that would guarantee future rematches. But as some have pointed out to me, maybe it happened a bit too late in their careers.

Jack Lemmon and Marcello Mastroianni (Macaroni) - Lemmon and renowned Italian actor Marcello Mastroanni in the same movie? What a fascinating idea, I thought! And the result definitely lives up to the expectations. They are so entertaining and believable as a couple of estranged/reconnected friends that you'd think he was playing against Matthau again. And with Ettore Scola's humanistic touch added into the mix you get something pretty special.
