Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
In what is reported to be the highest-grossing silent film of all time, an American solidier during World War One (played by Hollywood supertar John Gilbert) is sitting with a French girl at a small villiage in France when he sees a frog in the water then reaches out and grabs it. He doesn't speak French and she doesn't speak English so he holds it up and tries to explain to her that it's a frog and she's a frog (a derogatory term for French people in those days.) He finds out it's not the best way to gain her affection.
Most of the film was shot in Southern California, so it was probably a Baja California Treefrog, which in those days was called a Pacific Tree-toad.
