Film Stars Don't Die in Liverpool, 9.00pm, TG4
There are two great things about this cracking little film. One is that it’s based on a quite remarkable true story. The other is that Annette Bening is superb in the lead role.
Real life proves to be just as dramatic off-screen as it does on it for ageing Hollywood superstar Gloria Grahame (Bening) and her much younger lover, Peter Turner, played by Jamie Bell.
As their mismatched romance waxes and wanes over time, events conspire to keep them in each other's lives even when it proves to be difficult and demanding.
