This was shown on BBC2 last August. Initially looked interesting. However the more I watched the less interesting it became. Lots of talking heads,trying unsuccessfully,to conjure up her career in modern terms.
I have to say that the only film of hers that I actually saw whilst she was alive was Some Like It Hot. I have watched this numerous times and always find it funny. However she put the cast and crew through torture.60 takes because she couldn't remember one line. Nothing to do with Method acting,more to do with her drugs and drink intake.
Many of the claims made by the talking heads are fatuous and inaccurate..Rather a wasted effort.
