About The Greatest Power
Miriam Monroe and John Conrad are two young scientific workers who, independently of each other, have discovered a chemical called exonite. Miriam discovered it while searching for a cure for cancer, while Conrad used it as a basis for a powerful explosive.
Directed by Edwin Carewe, Edward LeSaint, The Greatest Power leans on a strong ensemble — Ethel Barrymore, William B. Davidson, Harry Northrup — to carry a story that balances spectacle with character.
The film landed with audiences for its craft and performances, and remains one of the most talked-about drama titles of 1917.
