Chris Gauthier — known for shows like “Once Upon A Time” and “Smallville” — has died … his agency confirmed in a statement.

The actor reportedly passed away suddenly Friday after recently falling ill with TriStar Appearances/Event Horizon Talent lamenting his loss to TVLine.

Tristar’s Chad Colvin wrote in a Facebook post that Gauthier was the very definition of a character actor … not an actor with a name one might know, but one whose sheer presence in a show or movie could pique the interest of any audience.

Gauthier appeared in a number of popular projects over the years including “A Series of Unfortunate Events,” “iZombie,” “Psych,” “Supernatural,” “Smallville,” “Watchmen,” “Agent Cody Banks,” “Little Man,” “Freddy vs. Jason” — and a whole lot more.

He was perhaps best known for his role in the TV show science-fiction show “Eureka” where he played gourmet chef Vincent in 67 episodes, and later as Mr. Smee — Captain Hook’s first mate in the ABC drama “Once Upon A Time.”

In fact, his ‘OUAT’ costar Colin O’Donoghue, who played Captain Hook in the series, also posted a touching tribute to Chris … saying he was the real captain all along.

Chris is survived by his wife Erin and their two children.

He was 48.
