A really interesting chick flick is The Notebook. Not because of the plot or anything like that -- but you get to see James Garner and Gena Rowlands blow two kid actors off the screen. You could almost sense they knew they were doing it -- "Yeah, the other two leads are pretty and youg, but we're gonna steal this movie by acting our old withered butts off!"
And you're right about Garner and Rowlands.
By the way, here's a pic of Messing. Don't we have rules around here?
With respect to older actors: just after Reagan left office, he was on some TV talk show (maybe Larry King?) and was asked what question was he asked the most often. Reagan said that he was most often asked about acting with Errol Flynn (even more than Iran-Contra).
Reagan also pointed out that the old character actors could steal a scene better than younger stars. Francis X. Bushman's performance in "Sabrina" is an example (as are most performances by Jack Elam or Walter Brennan.) John Wayne made a career out of letting (helping actually) other actors steal scenes. James Dean was coached on how to steal the scene in Giant where he is given the ranch by Mercedes McCambridge.
