The Guardsman (1931)

Synopsis
The legendary theatrical team of Alfred Lunt and Lynn Fontanne made their only starring screen appearance in this 1931 adaptation of Ferenc Molnar's The Guardsman. The Lunts are appropriately cast as a famous husband-and-wife acting duo, the husband of which suspects the wife of infidelity. To find out for certain, he disguises himself as an amorous Russian guardsman, complete with handlebar mustache. After an evening of paradise, Lunt confesses his subterfuge to Fontanne. She says she knew all the time, but that gleam in her eye opens up quite a few doubts which are never truly resolved. The fabled "naturalism" of the Lunts appears slightly strained under the probing eye of the camera lens, but their seemingly ad-libbed repartee sequences are a joy to behold. The Guardsman served as the basis for the Oscar Straus operetta The Chocolate Soldier, which itself was filmed in 1943 with Nelson Eddy and Rise Stevens. ~ Hal Erickson, All Movie Guide
