The plot concerns a well-meaning-but-ill-informed socialite widow who is appointed US ambassador to the fictional European country of Lichtenberg. While there, she and her press attache each fall in love with officials of the Lichtenberg government.
In CALLMEMADAM, Merman portrays Sally Adams- the Washington, DC hostess with the most-ess, whom President Truman appoints Ambassador to Lichtenburg, a small European Duchy roughly the size of Brooklyn.
For this cinematic version of CALLMEMADAM, Ethel Merman finds herself in very good company; Donald O'Connor is in top musical form, demonstrating his best dancing athleticism- both alone and with Vera-Ellen, plus O'Connor keeps up musically with Merman for their duet together.
Since CALLMEMADAM has been withheld from circulation for so long, it is possible that the sound elements havent been preserved quite as well as similar films from the same period.
