If you didn’t tune in to the first two parts of HBO’s magnificent mini-series “John Adams,” based on the book by David McCullough, I strongly urge you to catch them on On Demand. The series stars Paul Giamatti in the title role. Recent Academy Award nominee Laura Linney plays Abigail. David Morse, pictured above, Danny Houston and Tom Wilkinson also star. The 7-part series airs on Sunday evenings. You can find more coverage on my other blog.
