Bonus features include the Director's Diary with Dean Butler explaining some of the behind the scenes details of making this documentary, and includes trailers of Almanzo Wilder: Life Before Laura DVD and Pa's Fiddle.
Having grown up watching the series on TV, I found it interesting that Dean Butler pronounces Almanzo differently than they did on TV. It turns out, it is supposed to be pronounced Al-man-zo (like the word man)....hence the nickname, Manly....now it all makes sense. :) Read more about that here.
Watch the trailer.
