Someone was asking me about this, but I don't remember which thread, so I figured that I should start a thread for it now that I've seen it.
This movie was wonderful. It's framed by an older Cole Porter reviewing a musical about his life, and so it moves through his life as it were a musical incorporating all his songs.
The acting was good, and the music was great, they had some amazing performers. One word of warning, it's long, two hours and five minutes, but you don't particularly notice it. It doesn't hold back, it discusses his bisexuality, his self doubt, and his marital difficulties.
It's got some rather sad parts at times, but don't worry, never open with a ballad, and never end on one.
4 out of 5 stars.
