The ten-part HBO mini-series The Pacific is a follow-up to Band of Brothers from World War II-obsessed exec producers Tom Hanks, Gary Goetzman and Steven Spielberg. It follows a similar m.o.: hire excellent unknown actors to inhabit the characters we follow (Damian Lewis broke out from Band of Brothers). In this featurette, Spielberg describes how the soldiers not only faced a formidable enemy playing by unfamiliar rules, but a hostile natural environment. The series--which boasts a pricetag of more than $200 million, more than double that of 12-parter Rome--is the most expensive in HBO's history. It launches March 2010.
