Her Man Gilbey (1944)

While bird-fancier Lady Christabel Beauclark (Dame Margaret Rutherford) scurries around demanding certain territorial rights for British birds from other countries, Her Ladyship's niece is falling in love with the family's butler, Tom Gilbey (Michael Wilding). The birds are forgotten when war breaks out, and Gilbey now finds himself in love with the niece whose love was previously unrequited.
