Whatever the British-born German star Lillian Harvey possessed in such legendary Teutonic operettas as Die Drei von der Tankstelle and Congress Dances is completely absent in My Lips Betray, as leaden a soufflé as was ever served up on a Hollywood soundstage. John Boles, of course, was no Willy Fritsch, Harvey's partner in no less than 11 successful Ufa films, but the main culprits here are the cumbersome screenplay and, regrettably, Lillian herself, who comes across as almost aggressively coy. Add to that the supposed comedy relief of dialectician El Brendel -- an acquired taste under the best of circumstances -- and you have one of those flat-footed operettas that American audiences never really accepted.
