Opera is inherently weird: people singing their every speech. But with classical opera, one doesn't notice the effect so much, since they've always been around.
But relatively recent operas, especially with contemporary settings, somehow magnify the weirdness.
Take, for instance, 1964's THE UMBRELLAS OF CHERBOURG. A simple love story, it features a script in which every single line is sung. Thus, at about the 3:30 mark in the opening clip below, you can hear the immortal lyric, "Check the ignition on the gentleman's Mercedes."
Apparently, the entire film is available on YouTube in nine parts, for your operatic enjoyment.
