Trouble for Two is a 1936 American mystery film directed by J. Walter Ruben and starring Robert Montgomery and Rosalind Russell. It is based on The Suicide Club, a short story collection by Robert Louis Stevenson. A European prince, unhappy over an impending arranged marriage, finds intrigue at an unusual London club.

Robert Montgomery (; born Henry Montgomery Jr.; was an American actor, director, and producer. He began his acting career on the stage, but was soon hired by MGM. Initially assigned roles in comedies, he soon proved he was able to handle dramatic ones, as well. He appeared in a wide variety of roles, such as the weak-willed prisoner Kent in The Big House, the psychotic Danny in Night Must Fall, and Joe, the boxer mistakenly sent to Heaven in Here Comes Mr. Jordan. The last two earned him nominations for the Academy Award for Best Actor.
