General Crack is a 1929 American pre-Code sound all-talking historical costume melodrama with Technicolor sequences which was directed by Alan Crosland and produced and distributed by Warner Bros.

The film takes place in the 18th century Austria and revolves around Prince Christian, commonly known as General Crack (John Barrymore).

He espouses the doubtful cause of Leopold II of Austria (Lowell Sherman, reigned 1790-1792) after demanding the sister of the emperor in marriage as well as half of the gold of the Holy Roman Empire.

Complications arise when he takes his gypsy wife to the Austrian court and falls desperately in love with the emperor's sister (Marian Nixon).
