History's Greatest Mysteries (Seasons 1–7)

History's Greatest Mysteries (2020) is an American documentary series you can watch online on iFILM. Hosted by Laurence Fishburne, each episode takes one famous unanswered question and works it over from scratch.

The cases run from the sinking of the Titanic to hijacker D.B. Cooper's vanishing mid-air jump, from Roswell and its supposed saucer to what really became of John Wilkes Booth after he shot Lincoln. The show leans on declassified files, personal diaries and DNA analysis, testing which old theories hold up and which fall apart.

It plays things straight — less breathless speculation, more archive and expert input. Good for viewers who want genuine historical investigation rather than ufology chasing ratings. Stream History's Greatest Mysteries (2020) online on iFILM.
