Neil Patrick Harris has confirmed that Netflix's A Series of Unfortunate Events' third and final season has already wrapped filming...

And he's already really sad that he'll never again play Count Olaf, who's out to hunt down the Baudelaire orphans and claim the family fortune for himself.

"Can't believe that tomorrow is my last day as Count Olaf. For over two years I've gotten to play in the most creative, visual, challenging, fantastical sandbox of my career," he wrote on Twitter.

"I'm super proud, and will miss it greatly," Neil added.

Season three will cover the final books of the Lemony Snicket series: The Slippery Slope, The Grim Grotto, The Penultimate Peril, and The End. It'll take the Baudelaires further afield than before: to the top of a mountain, to the bottom of the sea, and to an absurd island cult.

Earlier this year, speaking exclusively to Digital Spy, Neil revealed why the decision was made to end the show on a high with its third instalment.

"That was always the journey, for everyone involved," said Harris. "I'm proud we're all doing something that's actually finite, and a piece of art. It's something that you can put on a bookshelf and appreciate for what it is, not just year after year hoping that people are still interested.

"It's another reason why the Netflix company is a great one to work for. It's allowing a very healthy budget to create a world unlike anything anyone's seen before. And it's a finite world. It's only going to be three seasons."

A Series of Unfortunate Events season 2 is on Netflix now.
