"My One and Only" follows actor George Hamilton's teenage years. It's an appealing comedy, a road movie set in the 1950s and starring Renée Zellweger as his mother, the irrepressible Anne Devereaux.

She's a blond Southern belle, married to Dan, a bandleader (Kevin Bacon) who loves her, but is a compulsive womaniser. After finding him in bed with one woman too many, Anne leaves him and takes her two sons: George (Logan Lerman) and Robbie (Mark Rendall), half-brothers from her two marriages. In a sky-blue Cadillac convertible, they set off an odyssey to find Anne a new husband - the only way she can imagine to support them.

Anne is 40-ish and attractive to men, but no longer this year's model. Their journeys take them to a series of her old beaus, in Boston, Pittsburgh and St. Louis; these hunting expeditions are seen through George's dubious eyes. One is an ex-military sadist, one a playboy, all not suitable candidates. She tries actually working, but being a waitress is beyond her, and then she apparently strikes pay dirt with a proposal from a man whose family owns a big house-paint business.
