I came upon this quite by chance on Talking Pictures whose output I enjoy 9 times out of 10. This was the one that misfired for me. Knowing the original Die Fledermaus very well I was somewhat flummoxed by the updating and by the serenely bad lypsynching of the actors. I'm not sure how Dennis Price and Anthony Quayle got themselves involved in this debacle but the sight - and sound - of the former tackling the "singing" was NOT a joy to behold.
