I purchased this film video on Amazon from a market trader as it was the only version of The Threepenny Opera available in English at the time. The quality looks like a typical fifties TV video, blurred and indistinct with poor contrast and definition.
This movie is the classic story of Mack the Knife. The version I saw was in the original German, and subtitled in English.
I've seen several stagings of this musical play-- even acted in it once in college-- and I have enjoyed the liveliness of every staging. The movie, however, is quite dead.
