Did Kevin McCallister — the little kid played by the long-ago-adorable Macaulay Culkin in the 1990 John Hughes blockbuster “Home Alone” — grow up to become Jigsaw, the demented serial killer from the seven-movie “Saw” torture porn franchise?

Writing at Grantland, Jason Concepcion entertains this compelling theory.

Most every American has seen “Home Alone,” which involves eight-year-old Kevin’s escapades after his family heads to Paris for Christmas and accidentally forgets him as he sleeps in his house in a posh suburb of Chicago. Kevin then defends his sprawling Winnetka residence from a pair of bumbling crooks, befriending Old Man Marley, his next-door-neighbor (thought to be “the South Bend Shovel Slayer”), along the way.

Concepcion sagely suggests the various pain-inducing contraptions Kevin sets to protect his house bear an eerie resemblance to the various death-inducing contraptions Jigsaw would use to kill and dismember his victims beginning some 14 years later — when Kevin would be out of college, and perhaps entitled to some trust fund enabling him to finance elaborate booby traps and kidnapping schemes.

“When you take into account the similarities between Kevin’s intricate, almost pathologically complicated home-defense mechanisms and Jigsaw’s carefully designed murder-traps, the case for Kevin being young Jigsaw become quite a bit more substantial,” Concepcion observes.

The Grantland writer notes that Kevin/Jigsaw appears to have been deeply scarred by seeing the furnace in the basement of the Winnetka house. Not surprisingly, a furnace plays an important, macabre part in the movie “Saw II.”

Also, the furnace in “Home Alone” looks remarkably like a ridiculous torture device that Kevin/Jigsaw would force a character to wear in his later work as a brutal, cancer-ridden lunatic.

Here’s the furnace in the Winnetka house:

Here’s the torture device in “Saw II”:

“It’s notable, I think, that most of Kevin’s home-defense devices are triggered by the victim, just as Jigsaw’s traps are,” Concepcion reflects.

Concepcion also notes the obvious similarities between the grown-up Macaulay Culkin and Jigsaw as played by actor Tobin Bell.

The next natural step is for a Hollywood producer to make a “Home Alone” sequel that is also a “Saw” prequel, helpfully suggests the A.V. Club.
