Robert De Niro debuted an HBO doc about his late artist dad at MoMA Thursday, and the remaining De Niro clan came out in force to support the “Raging Bull” star’s project.

De Niro’s wife, Grace Hightower, as well as his ex-wife Diahnne Abbott and former long-term flame Toukie Smith were there along with De Niro’s and Abbott’s grown kids Raphael and Drena and other clan members.

During an intro of Perri Peltz’s and Geeta Gandbhir’s film, “the question was posed, ‘How many De Niros are here?’ and half the audience’s hands shot up,” said a spy.

A Moore Gallery party for “Remembering the Artist: Robert De Niro Sr.” drew Christopher Walken, Denis Leary and Tony Bennett.
