Home Alone fans are pointing out glaring mistake in iconic scene

The big day is now tantalisingly close and for many us, the festive season is a great excuse to get cosy on the couch, tuck into some candy and binge classic Christmas movies.

And no Christmas is complete without a re-run of Home Alone as despite hitting cinemas more than 30 years ago, families across the US and the world will be tuning in once again to watch this popular nostalgic 1990s movie this December.

Although the comedy is a fan-favorite for millions, fans continue to conjure up new theories and spot 'mistakes' every year.

In case you've miraculously managed to avoid the movie, the plot follows the story of Kevin McCallister, played by a young Macaulay Culkin, who - spoiler alert - is left home alone when his family jet off to Paris for the holidays.

While the youngster is seen living out every kid's dream diet, indulging in mountainous ice cream sundaes and goblets of mac and cheese, eagle-eyed fans have pointed out one mistake in an iconic scene.

As Kevin carries his haul of groceries home in two plastic bags, the shop doesn't exactly go to plan.

The eight-year-old is strolling on the sidewalk before the two grocery bags suddenly burst open at the same time time, spilling its contents all over the ground.

And it's here where fans have spotted a problem.

The method used to make the bags break was not exactly well hidden, as the trick involves Culkin clutching some string between the handles of the shopping bags and, seemingly upon instruction, pulled the strings to break the plastic bags at the same time.

As well as the string trick, the cartons of milk and juice that spill out also appear empty.

Fans on social media claim the blunder continues to irritate them, as one person wrote: "Biggest pet peeve is empty containers!!! Fill them up with water at least."

Others have long queried how Kevin's family could've possibly 'forgot' to take the youngster with them, with some fans having noticed one tiny detail.

The night before the flight, Kevin argued with his older brother, Buzz, which resulted in a litre of milk being spilt all over the table and the plane tickets.

Kevin's dad, Peter, then 'accidentally' threw away one of the plane tickets when cleaning up the mess which viewers speculate could be why the family miscounted Kevin from the roll call.

A viewer wrote: "I’ve seen Home Alone ~25 times and it wasn’t until this most recent time I realised the dad threw away a plane ticket when cleaning up spilled milk at the beginning.

"That's why they never had an extra ticket."
