Frontiersmen is the new four-part docudrama executively produced by Leonardo DiCaprio that follows the stories of iconic pioneers, including Daniel Boone, Lewis and Clark, Tecumseh, Davy Crocket and Andrew Jackson as they set forth across the untamed land. The series will span across the first 75 years from the post-Revolutionary War colonies through the California Gold Rush, highlighting a formative period in U.S. history that helped shape us from colonists into today’s Americans.
