This short was one of the extras on the In This Our Life DVD that formed a Warner Night at the Movies link there. It attempts to tell in about 30 minutes the history of America at that point before then trying to stir patriotic sentiment after then showing a Japanese pilot flying toward Pearl Harbor, a dying American soldier using his bloody hands to form a V sign in a Nazi building wall, and various soldiers and tanks forming to go where they're needed. Filmed in Technicolor, this was quite exciting to watch though I couldn't help notice some glossing over some issues like that concerning the Civil War. And seeing that Confederate flag reminded me how unneeded it is today considering what happened at that South Carolina church last week. Still, March On, America! is interesting enough to watch as a historical document.
