A retired Upper East Side doorman who laments the end of stop-and-frisk has a surprise cameo role in an otherwise gushing online interview between actor Steve Buscemi and Mayor de Blasio.

While the rest of the segment features Hizzoner touting the accomplishments and goals of his young administration, Bill-backer Buscemi — to his credit — includes the retiree saying he’s grateful to former Mayor Mike Bloom­berg for bringing crime levels down.

The unidentified senior tells Buscemi the mayor should maintain the use of stop-and-frisk.

The clip is part of Buscemi’s online AOL series, “Park Bench.”
