The Lost Zeppelin is a 1929 sound adventure film directed by Edward Sloman and produced and distributed by Tiffany-Stahl. The film stars Conway Tearle, Virginia Valli and Ricardo Cortez.

Tearle plays a navy officer modeled on U. S. Navy Commander Richard Evelyn Byrd, who was then a national aviation hero. Byrd made his own genuine Antarctic adventure film, With Byrd at the South Pole, during his South Pole Expedition 1928-1929.

Plot

"Stella Maris" is a moving drama, in which Mary Pickford plays two roles very convincingly - one of Stella Maris, a rich paralyzed girl and the other of Unity, an uneducated orphaned girl.

Stella lives in a fantasy world, being shielded from the ugly side of life. She especially enjoys the company of John (Conway Tearle), a famous journalist.  He lives separately from his alcoholic wife called Louise, but this truth is also hidden from Stella.

Probably the only movie based on a novel by Harry Stephen Keeler. Note: there are many video dropouts during the first 5 minutes.
