There were a lot of great British films made in the Sixties as well as even more truly terrible ones. Of the bad ones, Joanna is quite possibly the worst. Bad acting, woeful writing, inept direction, horrendous music, overly artsy camera work...the only good thing about it was the costumes. Genevieve Waite in the title role looks lovely but that's about it. Equally bad is Donald Sutherland in a performance so appalling that you wonder how he ever had a career afterwards. And why on earth have Rod McKuen do the music for a film set in Swinging Sixties London?
In fact, the background is far more interesting than anything that happens in the film. At the end, Joanna gets on a train and says "I'll be back". Supposedly, audiences used to shout back "No! No!". Personally, I don't believe that story only because I doubt there was anybody left in the cinema by the end of the film.
There are lots of old and much better films that deserve to be released on DVD and/or BluRay. Who thought it was a good idea to resurrect this one from its well deserved oblivion?
