But the three Broadway veterans who comprise the entire cast give the play heft. Tony winner Burstein (Moulin Rouge! The Musical) is convincingly brash, letting dad’s insults fly right over him, while hiding an appealing vulnerability. Wanamaker is also terrific, resolutely going about her business and eventually even showing a soft side. And Broadway titan Nathan Lane doesn’t play down to his character, lands every laugh, and has a volcanic explosion late in the play that is brilliantly pulled off. Unfortunately, Irving—who describes himself as a deeply vulnerable person who doesn’t want to be seen as vulnerable—is pretty insufferable company, and director Bartlett Sher lets Lane exacerbate that by screaming so many of his lines. When Irv starts giving Larry the silent treatment out of seething resentment, you’re relieved for his vocal cords.
