SPRINGFIELD – City Councilor  Marcus Williams may be known for the legislation he has written or supported, but now he will be known for something else: acting.

Williams has been on the set of the Hulu series “Castle Rock” as an extra and is enjoying the experience. He wrote over the weekend, “So far, I’ve spent 11 hours on set and just got handed the green card – the official welcome to come back for more shooting tomorrow! Highlight so far: Standing next to Mr. ‘Shawshank Redemption’ himself, Mr. Tim Robbins!”    

Hulu recently renewed “Castle Rock,” a horror anthology series based on the stories written by Stephen King and based in the mythical Maine community of Castle Rock. Robbins and Lizzie Caplan are the stars of the second season.

The show is being shot in Orange and Devens, filling in for rural Maine.

Williams explained in another Facebook post, “Eleven years ago, I was blessed to run into an acting agent while going to school in New York. It would lead to being cast as an extra in the Brett Ratner-directed film ‘New York, I Love You’ and landing on an image campaign for AT&T with BBDO Productions.

“Eleven years later, a friend in the business reached out and advised me to submit for Hulu’s hit show ‘Castle Rock.’ I did. Today, I just received a call that I’ve been cast in Season 2 as ‘at least’ an extra and my fitting is tomorrow! This role eclipses the credits I need to join the Screen Actor’s Guild-AFTRA Union. Unconventional for a city councilor? Well, I’ve always been a non-conformist.”

Williams explained to Reminder Publishing his time 11 years ago with the Brett Ratner production was “an incredible experience.” He added, “It put a fire under me.”

If he works three days on the production he could apply for a Screen Actors Guild card and be part of that union, he added.

“If anything comes up in the future that [union membership] would be an easier route for me,” he said.

He admitted he was “a little rusty after 11 years.”

Williams participated in theater in both middle school and high school and had moved to New York City when he appeared in “New York, I Love You.” A transfer to Boston College meant an end to a career in show business and a focus on academics, he said.

Although he enjoys the opportunity, he has no intention to change his career plans and pursue acting.

“I think the city of Springfield needs me right now,” he added.
