I haven't seen "Second Hand Lions" yet but am looking forward to it. Did you see the one with James Earl Jones where Duvall finds out he has a half brother and it is JEJ? Can't remember the name of it but it was another one of my favorites.
It's excellent and not a little bit weird in parts, but really entertaining and funny. Both Duvall and Michael Caine are great.
The film with James Earl Jones (how did I forget to add him to my list of the top 3 or 4 actors?) was A Family Thing from 1996.
