The New York press, who have been unimpressed by many Hollywood stars' recent forays on to the stage, were captivated by the 25-year-old's performance in Arthur Miller's A View from the Bridge alongside theatre heavyweight Liev Schreiber.
"That the excellent stage veteran (Jessica) Hecht holds her own with Mr Schreiber is no surprise. That Ms Johansson does – with seeming effortlessness – is," wrote The New York Times.
The blonde actress donned a brown wig to play the role of Catherine, Liev’s character's teenage niece in the Fifties-set play.
It's thought Scarlett's husband Ryan Reynolds managed to jet in from the Sundance Film Festival in time to catch his wife's moment of glory at New York's Cort Theater, joining a host of other stars in the audience.
Ryan's X-Men co-star Hugh Jackman attended with wife Deborra-Lee Furness, as did actress Ellen Barkin, Star Trek movie star Zachary Quinto and Liev's film actress wife Naomi Watts.
After taking her bow, Scarlett swapped her beige stage dress for a bright floral number to join Liev and the rest of the cast at the opening night party at a venue in Manhattan's Clinton neighbourhood.
