7th Heaven (1927) (aka Seventh Heaven)

In Frank Borzage's pure and sentimental melodrama:

• the love scenes in the 7th floor bohemian loft ("Seventh Heaven") between street angel-waif Diane (Best Actress winning Janet Gaynor) and Parisian sewer worker Chico (Charles Farrell) after her attempted suicide by stabbing
• the spiritual nature of their relationship while he was called to fight in the war (and was blinded) and she was a munitions worker - when they telepathically communicated with each other through their hearts and minds at 11
• their jubilant reconciliation in an ethereal shaft of light
