This Home Alone fan theory will completely change the way you watch the movie.

We love a good fan theory.

We especially love a good fan theory about possibly the best home alone-based Christmas movie of all time… Home Alone ¯\_(ツ)_/¯. 

And this one is particularly… convincing.

You see, a Reddit user named cubanesis has shared the very plausible fan theory about Kevin’s dad, Peter McCallister.

The Redditor believes ole’ man McCallister could be “some kind of mid level criminal for the mob”.

Yep, it’s the Home Alone/The Godfather crossover special we never knew we needed in our lives.

“We never find out what he does,” the Reddit user explained. “They don’t mention where he works, or his background, or anything… But Peter makes enough money to have a wife that doesn’t work and like five kids. He also has a house that is worth like $1.5 million.”

The Redditor then went on to point out a few “suss” things the patriarch of the McCallister mob does in the film.

“The very first time we see Peter is when Harry [played by Joe Pesci] is dressed as a cop scoping the place out,” cubanesis wrote.

“Peter is WAY defensive in this interaction. All Harry does is ask if he’s the owner of the house and Peter jumps straight to, ‘Am I in some kind of trouble officer?’ The look on his face is on edge the whole time he’s talking to Harry.”

The very clever theorist also points out that Harry and Marv could have targeted McCallister’s house because he’s in the mob.

“Harry calls the McCallister house ‘The Silver Tuna’, the big score, etc… When we see in the house there’s nothing particularly valuable-looking around. We don’t ever see them mention jewels or a safe or anything like that, but still this house… is THE HOUSE to rob.”

Finally, cubanesis adds that the whole family acts a lil’ odd and mob-like.

“Kevin’s mum is a cold emotionally dead b***h who says terrible things to her eight-year-old son. Buzz is a… psychopath, who is probably set up to follow in his dad’s footsteps. Uncle Franks is obviously a crook of some kind. Then there’s Kevin, who seems completely OK with killing two robbers… He was out for blood.

“Plus, the whole family has terrible manners. Just look at the scene when Kevin’s mum is trying to use the pay phone in Paris and a woman is already using it. The whole family just muscles the poor woman off the phone.

“Also this jumps to the second film, but remember how much cash was in his bag that Kevin ended up with? He had thousands of dollars in cash. The early 90s were the time of travelers checks, plus they weren’t leaving the country, so there wasn’t a ton of reason to bring that much cash, unless you’re a criminal who deals in cash.”

After reading the theory, some other Redditors pointed out a few other suss moments in the film.

One person pointed out that perhaps Harry and Marv were hired by a rival mob family to take out the McAllister place. While another said the scene with the pizza boy screams mafia.

“Perhaps he told someone at the pizza company, and they were like, ‘yeah, go ahead and call the cops on the McAllister place … do you have any idea who lives there? You will die if the McAllister family (‘Family’ as in organisation) finds out you ratted on them,” nobody2000 wrote.

Well, we’re… convinced.
