Tom Francis asked to meet on a rugged corner of the Williamsburg neighborhood of Brooklyn. It was a bright April day, and in some ways Francis, 25, in a vintage sweater and slacks, looked like any other member of the creative class with a matcha habit. Still, I had picked him out a block away.

Onstage, in Jamie Lloyd’s coruscating Broadway production of Andrew Lloyd Webber’s “Sunset Boulevard,” his brooding features projected onto a 23-foot-tall screen, Francis looms large. But even here on Roebling Street, the actor, who stands 6-foot-2, with shoulders that would not demean a musk ox, was not exactly small. Francis is nominated for a Tony Award, and to see him pictured alongside his fellow nominees in the leading actor in a musical category is to believe that he could take any of them in a bar fight, maybe more than one at once.

His “Sunset Boulevard” co-star Nicole Scherzinger described him succinctly. “He is a man,” she said in a phone interview. But, she was quick to emphasize, Francis is also a sweetheart, “a 25-year-old teddy bear.”

In “Sunset Boulevard,” Francis stars as Joe Gillis, a dead-behind-the-eyes screenwriter who becomes entangled, in an asphyxiating way, with an aging queen of the silents. Here is the New York Times critic Jesse Green’s take: “Francis, as Joe, does shutdown-cynical-corpse very well.” Yet in person, Francis, who wields those shoulders lightly, is boyish, candid, eager, almost unable to believe his good fortune.

And yes, that good fortune requires him to remain onstage for nearly every moment of a two-and-a-half-hour mega musical, except when he is leading the cast — in wind, in rain, amid tourists — through a portion of the Theater District as he sings the title number outdoors. He ends the show in his underwear, sunken-eyed and covered in blood.
