Australian cult comedy blogger David Thorne has confirmed new forays into TV, with an eight-part HBO series and a one-off snowboarding mockumentary with Chris Lilley.

Thorne sprang to fame while working as a graphic designer in Adelaide in 2008 by attempting to pay an overdue bill with a spider drawing. His bold, wry humour and mock harassment of neighbours, colleagues and his son’s teachers have gained him consistent viral popularity since then, spawning a New York Times bestselling book in The Internet Is A Playground, and now, new TV projects. 

The Lilley project is a one-hour mockumentary starring the pair, called Cold Feet: America's Bunny Slopes. "It's about two individuals who embrace the snowboarding culture to the fullest extent but do not know how to snowboard," says Thorne.

"Chris plays Derek, a Shaun White devotee to the extent of dying his hair red, while I play his best friend Josh who spends more time trying on different outfits and buying new gear than on the snow.

"Chris and I first met a couple of years ago at a function and share a similar sense of humour. In his words, 'We're like peas in a pod. Except I'm talented and famous'."

Cold Feet will air in the US in August and in Australia and Britain in September, followed by a DVD release in October. 

The HBO series is being developed with Jim Vallely, an Emmy-winning writer and producer of Arrested Development. Thorne says the series is set in a design agency and has been described a cross between "The Office and Eastbound & Down". 

"I would describe it more as a modern day Tom & Jerry," says Thorne. "But it’s not a cartoon. It does have a cat in it though."

Thorne said casting will be begin next month, with filming starting in September and an air date of next February. 

Thorne now lives in Virginia with his American wife, Holly. He also released a second book, I'll Go Home Then, It's Warm and Has Chairs, in 2012. He says he signed up to LA creative agency ICM partners last year after being approached about the TV rights for his website.

"I signed a few contracts, sat uncomfortably in on a few meetings, and rewrote scripts written by writers brought in."

David Thorne's mischief:

Overdue account: The original piece that brought Thorne to fame, in which he tries to pay a bill with a drawing of a spider. "I value the drawing at $233.95 so trust that this settles the matter."

Missing Missy: A colleague asks him to design a poster about her missing cat. "As Missy has quite possibly met any one of several violent ends, it is possible you might get a better cat out of this."

Matthew's party: Thorne misinterprets a neighbour’s note about potential noise from an upcoming party as an invite. "Also, I have arranged a Pinata."

Permission slip: Thorne responds to his son’s school chaplain after a note about an Easter presentation. "I have received your permission slip featuring what I can only assume is a levitating rabbit about to drop an egg on Jesus."

10 formal complaints: Formal paperwork submitted by Thorne’s colleague Simon, complaining about incidents such as having his business cards replaced "with cards that have my title changed from graphic designer to horse whisperer".
