What's on TV: Thursday, February 1

SBS, 8.35pm

Frisky monks. Fair maidens. Noble warriors. This sword and chain-mail take on the downfall of the Knights Templar could have been a historical jaunt to rival Vikings or Game of Thrones, but Knightfall nails its colours to the mast of gobsmackingly awful from the opening credits, when what looks like a leak from a Heinz family ketchup pack cascades down a knight's visor. The hairy cast includes a number of Downton Abbey refugees who do their best with the plodding material, but it's not too far removed from the absurdities of Monty Python. In fact, Knightfall could fall within the exalted category known as "so bad it's good". Now that's a Holy Grail indeed. Larissa Dubecki

The Girlfriend Experience
SBS Viceland, 9.30pm

A typically enigmatic performance from Riley Keogh (Elvis' grand-daughter, thank you very much) gives ballast to the arthouse pretensions of this somewhat troubling series about a young woman who's a legal intern by day, a high-end sex worker providing "the girlfriend experience" to rich, bored men by night. A Sphinx-like beauty who betrays few emotions, Keogh's mystery holds together a plot that's equally elliptical but problematic – beautifully, coolly shot but one that bases its inevitable trajectory on the ritual humiliations endured by sex workers both high and low. Larissa Dubecki

Movie High Plains Drifter (1973)
Fox Classics (pay TV), 11.50am

Clint Eastwood's extraordinary career began as an actor on television (specifically Rawhide) and then in Spaghetti Westerns (A Fistful of Dollars), before picking up a Magnum .44 as Dirty Harry. Many of these early outings were good, or better, but who could have imagined Eastwood would become the revered figure he is today, as actor-writer-producer-composer-director. It is therefore fascinating to return to his early Westerns, such as High Plains Drifter, which stands comparison with anything he has done since. In a sequence both eerie and malevolent, The Stranger (Eastwood) rides into the desolate lakeside town of Lago, where he kills three Lago Mining Company gunmen and rapes a woman. Instead of getting upset, the Company offers him anything he wants to protect the town. But when people make Faustian bargains, they usually get far more than they bargained for. Eastwood's critique of corporate capitalism, and human weakness in the face of it, is scorching. Scott Murray

Pay The Great Australian Bake Off
Lifestyle, 8.30pm

It's clear that to be involved in The Great Australian Bake Off in any capacity you need two things. One is a signature biscotti recipe. The other is the ability to take a double entendre and then knead, roll and fold it so brutally that it becomes almost indistinguishable from a single entendre. Some of tonight's lewder allusions test the bounds of what can be gotten away with in the context of a baking show aimed at a general audience, but Sir Les Patterson would no doubt approve. In any case, there's plenty of creativity and technical skill on display, and a lovely warmth among the contestants, judges and presenters. It's biscuit week, so the contestants are soon busying themselves with trays of biscotti and jam-drops before having to design and bake their own edible biscuit jigsaw puzzles. Good stuff.
