HBO has just posted the first trailer for The Pacific, its upcoming miniseries companion to its 2001 hit Band of Brothers. (See embedded video below.)

The spring 2010 event is from the same production team, led by Tom Hanks and Steven Spielberg. This time, the focus is on the Pacific front of World War II, as seen by three Marines (played by Jon Seda, Joseph Mazzello and James Badge Dale).

After the mammoth success of Band of Brothers -- both on the air and on DVD/Blu-ray -- anticipation for The Pacific is pretty intense. One fan site has been chronicling the epic project's making for two years already.

By the way, Band of Brothers gets another full-length airing on History Channel next Monday-Tuesday, June 29-30. The first seven parts air Monday (10:42 a.m.-8 p.m. ET), with the final three parts Tuesday (9:11 a.m.-1 p.m. ET). Project background from History here.
