Last year there was a delightful, inspirational documentary, Mad Hot Ballroom, about Pierre Dulaine's successful scheme to bring self-respect, courtesy and discipline to New York's ghetto schoolkids through competitive ballroom dancing. Take the Lead is a fictionalised version of how it got started. Antonio Banderas stars as Dulaine, the gifted gentlemanly proprietor of a dance academy who takes a detention class of black and Hispanic no-hopers and turns them into a team of winners. Unlike Strictly Ballroom, which was an aff ectionate send-up, this is a deadly serious movie, full of uplift, and might well have been marketed as 'Strictly Hokum'. The kids, all professional performers, look a trifle old for high school pupils. In fact some wouldn't look out of place as mature students at Birkbeck College.
