Dangerous Innocence is a 1925 American silent romantic comedy film written by Lewis Milestone and James O. Spearing based upon the 1923 novel Ann's an Idiot by Pamela Wynne.
[1][2] On a ship sailing from England to India, Ann Church (Laura La Plante) meets young and dashing Major Anthony Seymour (Eugene O'Brien), falls in love and makes some innocent advances to gain his attentions.
The Major at first resists her advances because he believes she is that young, and later he holds back after learning that Ann's mother Muriel (Hedda Hopper) was his ex-girlfriend.
Approximately one half of the scenes were shot on board the SS Calawaii of the Los Angeles Steamship Company during 14 days during a round trip voyage from San Francisco to Honolulu, Hawaii.
They conclude that the film "is a photoplay which can be enjoyed because of the appealing love story and the pains taken by the producers to give an idea of the background, both aboard ship and in India.
