Gotham’s Roundabout Theater Company has confirmed a toplining Broadway stint for Frank Langella in “Man and Boy,” the 1963 play by Terence Rattigan.

Maria Aitken, who helmed the Roundabout outing of “The 39 Steps,” directs.

Langella will play a desperate, Depression-era businessman who seeks out his estranged son while attempting to save his company. Play has not been on the Main Stem since it played a seven-week run in 1963.

Langella’s last role at the Roundabout was in the 2008 revival of “A Man for All Seasons.” Aitken’s most recent Roundabout gig, “The 39 Steps,” went on to commercial transfers, first on the Rialto then Off Broadway.

It’s the centenary year for late Brit scribe Rattigan, whose plays “Cause Celebre” and “Flare Path” have been seen in recent London stagings.
