Not at the farcial level of Mel Brooke's "Blazing Saddles", but full of tongue in cheek, and slapstick humor plus winking, cultural commentary, Gunless is a lot of fun!
Paul Gross(quite well known in Canada, I remember him from the "Red Green Show") plays a, set in his ways, American gunslinger that flees into a bucolic, Canadian town being chased by, ever getting nearer, bounty hunters. He gets in a huff with the local, giant of a man, blacksmith and determines to have it out with him if, and a big if, he can find a working six shooter for the showdown.
He takes a job, a trade off, put up a windmill for a gun, with a pretty but struggling rancher, Sienna Guillory("Inkhart", "Resident Evil"). The townfold are quirky and charming and with the woman do there best to distract him from his plan.
It's well shot and scripted, nice scenery, and there's enough seriousness to it to keep it more in reality than just being a constant joke; moreover, the hero and heroine provide a sweet, developing, but at odds, romance. My wife won't watch a western unless there's some hint of romance or at least a woman in it.
It's not quite full family fare: the baddies shoot a dog, threaten townfolk, attempt a hanging, but overall, the violence is controlled and made fun of, the language, except for the outtakes, minimum; there's no nudity or sex, one implied encounter, and all things work out for the best with a moral about living peacefully.
Summary, a feel good movie, an unusual, comedic western, that also pokes light fun at cultural differences between US and Canada.
