Of note, Now We're in the Navy was directed by Brooks' husband of the time, Eddie Sutherland. And, it includes a nod the the director's wife. One of the small boats in the film is named "Louise."
But what's more, Brooks herself was on hand at a benefit pre-release midnight showing of the film at the Rialto Theater in New York City on November 5, 1926. Eddie Sutherland, was also on hand, as was Betty Bronson, Ricardo Cortez, Richard ‘Skeets’ Gallagher, William Powell, Evelyn Brent, and Philip Strange. Helen Morgan sang to the crowd.) The event was a benefit showing in aid of the New York American Christmas and Relief Fund. The film would prove to be a huge hit, and would enjoy extended runs in a other cities.
I haven't yet seen the Grapevine release, so I can't speak to its quality. More information on the Grapevine release can be found HERE.
