Although generally speaking this is an interesting series about the actors in question it is the barrage of so called experts who can't possibly know the biographical stuff,that spoil it.In particular the Eli Wallach episode has Bonny Greer ,better known as an author and political pundit who appears to know all about Wallach.Who could've guessed? .She's not alone.Various individuals some about 20 years old,seem to know stuff too.Amazing! It's almost as if they'd been fed the stuff.
This habit is not confined to this series.If you ever watch rock star biogs on BBC4, it is amazing how much these people know who weren't born until after the subjects career had finished.
Could it possibly be a way to get the yoof to watch?
