Lilac Time is a 1928 American synchronized sound romantic war film directed by George Fitzmaurice and starring Colleen Moore and Gary Cooper.

[4] Lilac Time offers several phases, beginning with slapstick comedy elements, becoming an intense romantic film, then segueing into a spectacular aerial showdown.

This was followed by a duel in the sky between Cooper's character and the "Red Ace" before returning to romantic complications.Seven young English aviators are billeted at the Berthelot farm near the French front.

Jeannie sends a bouquet of lilacs to his room in remembrance, and Philip, recognizing the flowers as her gift, painfully drags himself to his window in time to call her back to him.

The theme song of the film was entitled "Jeannine, I Dream of Lilac Time" and was composed by Nathaniel Shilkret with lyrics by L. Wolfe Gilbert.

Lilac Time was shot on sets at First National's Burbank studio and on location in El Toro, California, where a working airstrip, full-sized French village and farm serving as a base for a fictional Royal Flying Corps squadron, were built.

[8] Lilac Time had its opening in Los Angeles at the Carthay Circle Theatre where, in the lobby, among other promotional materials on display, was the wrecked fuselage of one of the aircraft that had been destroyed during the filming.
