I went to IMDB.com and found out that James Gandolfini is indeed going to appear in a movie with Ben Affleck that's due to be released in 2004. The movie is called "Surviving Christmas" and the tagline is "A lonely guy rents himself a family for the holidays." It seems as if Affleck is the aforementioned lonely guy. Also in the movie is Christina Applegate of "Married with Children" fame.
