“Bucky Larson: Born to Be a Star” is the tale of a small-town boy from Iowa, with a Prince Valiant haircut, a bad overbite and big dreams, who comes, like so many other small-town dreamers, to the San Fernando Valley to become a pornographic film star. There he meets a bunch of other performers who seem to be desperate for work and willing to submit to unimaginable degradation for a chance to appear on the big screen.

I’m not talking about the characters in “Bucky Larson,” which was directed by Tom Brady (“The Hot Chick”) and written by, among others, Adam Sandler. I mean the supporting cast, whose names I almost hesitate to mention for fear of embarrassing them. Nick Swardson, who plays Bucky and who is also one of the credited writers (Allen Covert is the third), seems immune to any such shame. With more energy than wit, he takes his turn as the latest overgrown man-boy to make funny faces and funny voices in an R-rated comedy.

“Overgrown” that is, in all respects but one. Bucky, who has reached whatever age he is supposed to be — 35? 40? — in a state of complete ignorance about the most basic sexual matters, turns out to be a fellow of exceedingly modest endowment. But this shortcoming proves to be his ticket to stardom, since watching his, er, performances makes average men feel better about themselves.

It occurs to me that “Bucky Larson: Born to Be a Star” may have been made for a similar purpose, to console every actor who has ever been in a movie that is a little less bad than this one. Let me put the matter another way: this may be the worst movie Pauly Shore has ever been in. Think about that. If you dare, go on Netflix and test the hypothesis.
