Beloved actor Isiah Whitlock Jr. — perhaps best known for his catchphrase “Sheeeeeit…” from “The Wire” — has died.

The Hollywood veteran passed away peacefully Tuesday in New York following a short illness, Deadline reports.

Whitlock starred as corrupt Senator R. Clayton Davis on “The Wire” and had recurring roles on “Veep,” “Your Honor,” and “Atlanta.”

Whitlock collaborated with Spike Lee on several film projects, including “25th Hour” — where he originated his signature phrase — “BlacKkKlansman,” “Da 5 Bloods,” and “Chi-Raq.”

Whitlock’s manager Brian Liebman told Deadline, “Isiah was a brilliant actor and even better person. He was loved by all who had the pleasure to work with or know him. He will be greatly missed.”

He was 71.

Sean Astin is stepping in to help ‘Ned’s Declassified’ alum Tylor Chase … according to one of his former costars.

Daniel Curtis Lee, who’s recently spent time with Tylor — even covering a temporary hotel stay for him — tells TMZ … shortly after seeing him, someone assisting Tylor reached out, and told him Sean Astin wanted to meet Tylor.

According to Daniel, Sean — a major hero to Tylor, who’s a huge “Lord of the Rings” fan — hoped the meeting might help convince Tylor to get off the streets.

On Christmas Day, Daniel spoke with Tylor over FaceTime, during which Tylor reflected on his experience meeting Sean … and by the sound of it, it was a positive one. Worth mentioning, Sean is the current president of the Screen Actors Guild.

The push to help Tylor came after videos circulated the internet, showing him looking unkempt and in need of housing.

Riverside Police spokesman Ryan Railsback previously told us law enforcement can only do so much for Tylor without him explicitly asking for or consenting to help.
