‘Big Bang’ star slams ‘Jeopardy’ host for crossing WGA picket line

His reputation could be in jeopardy – literally.

In a scathing message on Facebook, actor Wil Wheaton blasted “Jeopardy!” host Ken Jennings for crossing the picket line during the Writers Guild of America strike, giving him a stark warning.

“This is a VERY small town, Ken Jennings, and we will all remember this,” “Star Trek: The Next Generation” star Wheaton wrote on the social media platform. “Your privilege may protect you right now, but we will *never* forget.”

“#WGAStrong,” he added.

The “Big Bang Theory” actor continued his thoughts in the comments section of the post, calling out those who were speaking negatively about unions.

“Hey y’all, if you’re here to s–t on unions, you can f–k right off. I’ve been a union man since I was a union boy, and I will be a union man until the day I die,” he wrote.

“If you’re here to s–t on the workers of the world, or to make excuses for someone who is currently doing that, go f–k yourself and don’t come back.”

The Post reached out to reps for both Jennings and Wheaton for comment.

Last week, an insider confirmed to The Post that Mayim Bialik had exited the show during its final week of filming for Season 39 in support of the ongoing WGA strike.

In place of Bialik, Jennings took on hosting duties – a gig that Wheaton, and other writers, don’t seem to be too fond of, Newsweek reported.

Wheaton himself was a contestant on “Celebrity Jeopardy!” last year.

On May 2, the WGA announced that its members would be going on strike in an effort to petition for higher wages, regulation surrounding artificial intelligence and a better pay structure from streaming services.

“The companies’ behavior has created a gig economy inside a union workforce, and their immovable stance in this negotiation has betrayed a commitment to further devaluing the profession of writing,” the WGA said in a statement, The Post reported.

“From their refusal to guarantee any level of weekly employment in episodic television, to the creation of a ‘day rate’ in comedy variety, to their stonewalling on free work for screenwriters and on AI for all writers, they have closed the door on their labor force and opened the door to writing as an entirely freelance profession,” the statement continued.

The work stoppage has affected many television shows, shutting down production of this season’s “Saturday Night Live” and “The Late Show With Stephen Colbert.”

The union represents more than 11,000 writers in the entertainment and media industries, according to “Today.”

The last writers strike occurred from November 2007 to February 2008.

In 2017, a three-year deal was reached between writers and producers to avoid a strike.
