Sharon Stone lights up a romantic comedy that without her would be fairly ordinary.

She plays a struggling LA fashion designer, a flighty singleton who goes from one casual hook-up to the next without settling on a relationship – to the chagrin of her devoted mother (Ellen Burstyn, proving Stone’s worthy foil).

We follow her over a series of six birthdays, starting with her 46th when her best friend tries disastrously to set her up with an uptight lawyer (Tony Goldwyn).

The pair are typical romcom opposites – she’s free-spirited, he’s starchy – so we know exactly where the film is headed. Even so, Stone is such captivating company that it’s worth hanging around. First-time writer-director Susan Walter’s script may be lacklustre, but Stone dazzles.

This film premieres on 14 October.
