The Heart of Ezra Greer is a 1917 American silent drama film produced by the Thanhouser Company and directed by Emile Chautard.

The film focuses on Ezra Greer, a successful middle-aged man who searches for his college age daughter, Mary.

After a carriage accident in which the baby is injured, Ezra and Jack rush to the hospital and find Mary as a nurse crying over the child.

He cares deeply for his motherless daughter, Mary, but was unable to attend the annual commencement at her co-educational college.

Without word from his daughter, Ezra resigns from his job and attempts to seek her out and finds a poor motherless child, Marie.

Not knowing he was making the case for his own daughter, Ezra convinces Jack to seek out Mary and forget the Baby Vamp.

Q. David Bowers writes that it was easy to understand Thanhouser's decision to retire due to numerous aspects including that releases through Pathé were based on their decision to release or discard the work, the New Rochelle studio was 2,500 miles from the center of the trade activity and the slump in industry tied to World War I.

[3] Little is known of the production of this final film, but it was directed by Emile Chautard from a scenario written by Lloyd F. Lonergan.

[1] Charles E. Wagner of the Exhibitor's Trade Review found it to be a good film with great direction and photography, but was concerned that the stunt in which the baby appeared to be involved in the accident was too real.
