Stephen Colbert's final week hosting "The Late Show" took on ceremonial weight Wednesday as five major comedians and actors participated in his signature "Colbert Questionnaire" segment. Billy Crystal, Robert De Niro, Tiffany Haddish, Aubrey Plaza, and Ben Stiller filed through the interview format that has become one of late-night television's most recognizable recurring bits.

The questionnaire, borrowed from the French publication Vanity Fair, has defined Colbert's approach to celebrity conversation since his CBS tenure began in 2015. Rather than standard promotional chitchat, the format asks guests the same battery of personal questions, creating a shared language between host and visitor. Celebrity participants answer queries about their first crush, their defining childhood memory, or their greatest extravagance, producing moments both comic and revealing.

Wednesday's parade of A-list participants functioned as a farewell apparatus. Crystal, the veteran comedian and Oscar host, brought decades of industry standing. De Niro represented prestige cinema gravitas. Haddish embodied contemporary comedy's rising generation. Plaza and Stiller, both products of the indie-comedy ecosystem that overlaps with Colbert's own sensibilities, completed the roster.

The episode aired as Colbert prepared for his final "Late Show" broadcast Thursday, May 16, concluding a nine-year run that reshaped late-night television's political voice. His combination of satirical precision, literary reference, and genuine emotional intelligence pushed the format beyond celebrity interviews and comedy bits toward something resembling actual cultural commentary.

By inviting collaborators and peers to participate in his most recognizable segment, Colbert's producers created a valedictory moment that honored the show's distinctive DNA. The questionnaire, once borrowed from print culture, had become inseparable from Colbert's brand. Its final iteration, populated by Hollywood friends, transformed a comedic interview device into something approaching an institutional memory.
