Jim Carrey, he of “Ace Ventura: Pet Detective” and “Dumb and Dumber,” looks to have been inspired by the movie “Trace Amounts” when he denounced California’s tough new vaccine law.

“Go to traceamounts.com watch the documentary and judge for yourselves,” he wrote on Twitter, after referring to Gov. Jerry Brown as a “corporate fascist” for signing Senate Bill 277 on Tuesday. “If you really care about the kids you will. It’s shocking!”

Carrey maintains he’s not anti-vaccine; but like others, including Robert F. Kennedy Jr., who screened the documentary in Sacramento, he questions their safety. Vaccine makers say they have removed the mercury-based preservative thimerosal, a chief point of concern, out of all but some flu vaccines.

Though he’s being roundly ridiculed for his persistent criticism, it’s won Carrey praise from some of the people looking to overturn the law. Republican Tim Donnelly expressed his gratitude toward the actor before turning to more pressing matters.

A former assemblyman and gubernatorial candidate, Donnelly launched the referendum effort on Wednesday, giving him three months to collect 366,000 signatures. That will take money, and Donnelly (no stranger to celebrity partnerships) had just the guy to ask.

“Filed #SB277Referendum today,” Donnelly informed Carrey, on Twitter. “Can you help us raise $$$ and awareness? #stopsb277 #SB277 #noSB277”

The comedian didn’t respond publicly. For Donnelly that calls to mind one of Carrey’s famous movie lines: “So you’re telling me there’s a chance.”
