Hoffman got a little carried away and even jokingly jumped on the actress after being provoked by the show's host last week.
Hoffman, 77, first talked about how creative he has to get when he's at ballgames with his wife, Lisa, because the camera lingers until the couple locks lips. What to do the next time the camera catches them, and the time after that, Hoffman said, is another concern.
One time, Hoffman and Bateman decided they would go to the game together and Hoffman would pull a fake out. Hoffman said the plan was that he would pretend to lean in to kiss his wife and, at the last second, turn away and then kiss Bateman, instead.
Norton showed actual pictures of the two actors kissing at a game in 2010 to the delight of the audience.
As a joke, Norton had a kiss cam of his own and focused it on Hoffman and Dench, 79.
Hoffman immediately gave the famed actress a passionate kiss that lasted almost 10 seconds.
Wait until about the 2:45 mark on the video -- that's when the magic happens.
