Out of a Clear Sky is a lost[1] 1918 American silent romantic drama film starring Marguerite Clark and directed by Marshall Neilan.

Based upon a novel by Maria Thompson Daviess, Famous Players–Lasky produced the film and Paramount Pictures distributed.

[2][3] As described in a film magazine,[4] Celeste (Clark), Countess of Bersek et Krymm, a self-willed Belgian maiden, refuses to be used as a pawn of state to further the political ambitions of her scheming Uncle Dyreck (Ratcliffe), who has ordered her to marry a German prince.

A prey to despair, she is discovered by Robert Lawrence (Meighan), a wealthy land owner, who promises to help her.

Learning that Uncle Dyreck is in the vicinity, Robert leaves Celeste and seeks him out to throw him off the scent.
