lock up your daughter be one of the best high spirited comedy i have ever see . it be misunderstand since it lack the social commentary value that many film of the day ( 1969 ) require to be successful . the character be over the top satire of everyday people and play to that purpose by all of the actor . christopher plummer shine especially bright a lord foppington and a noble with hair too big to fit in the door . the plot involve the usual 18th century stuff while mistaken identity and thwart romance and corrupt government official and and joke at every turn . it answer the question represent what happen when 4 rambunctious and eager to party sailor be on leave in a small british coastal town . and and who do they get involve with and how do it all turn out . despite do poorly at the box office and it have great costume and excellent music ( base on the mermaid theatre musical of the same name ) and great and lively acting and set that be obviously authentic . that it have never be release on either vhs or dvd be truly a shame and since so many bad movie be release every day .
