This is the second movie that I know of, that came from someone's suggestion here at "freerepublic.com". The other one was "Anger Management" and I've known of several commercials generated from here, such as "The Romin' Gnome" and the firing of William Shatner on "PriceLine.Com".
I haven't seen "Anger Management." "Secondhand Lions" came to my attention via the recommendation of a friend. And I ordinarily avoid Michael Caine, go figure. It's so nice to be pleasantly surprised by a movie!
