"[10] Ben Brantley of The New York Times wrote that "When Nicole Kidman steps out of the shadows, breaking off from a wall of men, and onto the edge of the stage at the Noël Coward Theatre...her eyes beam undiluted willpower.

"[11] Paul Taylor of The Independent wrote that "In her compelling and subtle performance, Kidman beautifully captures the prickly defensiveness, the lonely dedication, and the suppressed emotional longings of the scientist.... Michael Grandage's superb 91-minute production expertly balances its energies as detective thriller and as interactive speculation about the hovering moments where her life could have taken a different turning.

"[H]er performance is muted but reliably intense, hinting at wounded depths beneath Franklin's implacably chilly exterior....Grandage's production is a worthy effort, but a little passionless, inherently limited in dramatic force by its subject matter.

and "Although the supporting male performances suffer from scantily written roles, Grandage directs it all with characteristically fluid aplomb, placing the action (sometimes using neat, quasi-scientific symmetries) amid a towering set by Christopher Oram that evokes the bombed-out Palladian magnificence of King's, piles of rubble lapping at arches.

Neil Austin's forensic lighting, cutting through clouds of haze, sees to it that as Edward Bennett and Will Attenborough's Crick and Watson finally unravel a secret held from mankind for millennia, all hint of rosiness in Rosalind's face vanishes, a deathly pallor taking its stead.

Edward Bennett and Will Attenborough combine vigorously as Francis Crick and James Watson, whose names are today synonymous with scientific sleuthing, and Stephen Campbell Moore brings just the right degree of donnish clumsiness to Maurice Wilkins, who shared their Nobel Prize in 1962 (four years after Franklin's untimely death).

She captures the obsessive nature of a woman dismissed by Watson as being “sticky” and having an “acid smile”, while suggesting the complexity beneath her severe façade – an inspiring mix of passion, pride and vulnerability.

This time her kit remains on, and dowdy: Franklin has eyes only for her X-ray crystallography work on DNA at King's College, London, without which Crick and Watson over in Cambridge would almost certainly not have cracked the secret of the double helix.
