British Agent is a 1934 American romantic espionage film directed by Michael Curtiz and starring Leslie Howard and Kay Francis.

In the days leading up to the Russian Revolution, Stephen Locke, a minor British diplomat, watches rioting in the streets.

He is to try to prevent Soviet Russia from concluding a separate peace with Imperial Germany, which would free up large numbers of German soldiers for the Western Front, but he is warned that he is only an "unofficial" British representative.

He manages to get a delay of three weeks to see if he can persuade his superiors to agree to Soviet demands: £50 million, five army divisions and munitions.

Instead, without Stephen's knowledge, the British send a force to Archangel to fight alongside the internal enemies of the Soviets.

After the Tsar is executed, Medill, LeFarge and Del Val persuade Stephen to join them in supporting counterrevolutionary forces.

At one point, the studio considered the possibility of shooting some scenes on location in the Soviet Union, but the political situation there made that impossible.
