I'd prefer to see a dramatised TV series about 'the rise and fall of Motown' than a movie about the Supremes. A Supremes movie would no doubt end with the credits rolling as the girls sing 'Someday We'll Be Together' in Diana's final concert with them.

A multiple-series TV show from the earliest days through to - say - Thelma Houston could show the interlocking stories for just about everyone with the dramas of racism, drugs, deaths, rivalries, jealousies and all the other rumours and scandals plus all those great songs.

But - it would need all those songs.
