Book? What book? That would seem to be the bone of contention, if you will. Ben Karlin, former headwriter for The Daily Show, has filed a lawsuit against TV chef Mario Batali and actress Gwyneth Paltrow claiming they did not pay him for work he did for a book on which they were collaborating. Karlin, who shared authorship of America (The Book) with Jon Stewart, says he was assigned to "conceptualize and oversee" a book to compliment a PBS series starring Mario and Gwyneth in which the stars take a cultural and gastronomic tour of Spain. The series, which may be called Spain...on the Road Again, will premiere this fall.
