People are just finding out how original Spider-Man trailer had to be changed because of 9/11

People are only just seeing an old trailer for the 2002 Spider-Man movie, and one detail has left them shocked.

For many people, the 2002 movie is the definitive Spider-Man film - sorry Andrew Garfield and Tom Holland.

Tobey Maguire took on the role of Peter Parker, the teenager who finds himself bitten by a genetically-modified spider while on a school trip.

The movie features J.K. Simmons in an iconic performance as perpetually furious newspaper editor J. Jonah Jameson, who hires Parker to take pictures of Spider-Man.

But despite the film going on to be a success with two sequels, an early trailer for the film had to be pulled due to one rather large problem.

The movie may have been released in 2002, but promotional campaigns, including teaser trailers, were run in 2001 - and filmed earlier still.

This meant that large parts of the film had to contend with New York being struck by 9/11.

And one trailer in particular had to be scrapped as it featured the World Trade Center very centrally.

The trailer begins with a shot of a helicopter suspended in one of the eponymous superhero's webs.

It might seem innocuous, but the camera then pans out to reveal that the web itself has been strung between the two towers of the World Trade Center.

The 9/11 attacks saw the towers destroyed after being hit by two passenger jets hijacked by members of Al-Qaeda.

Including the 19 hijackers, 2,997 people were killed in the attacks.

So, understandably, any footage that centred the towers was immediately pulled as being in poor taste, including the trailer for Spider-Man.

People took to the comments to share their thoughts.

One person was stunned, saying: "i jus[t] found this out, that first part is insane."

Another had a rather different observation about the quality of the CGI, saying: "How is the CGI from way back cooler than now?"

But many people were all left saying the same thing about the trailer.

It's fair to say that the style of trailers has changed a lot over the past few years.

And many people were acutely aware of this change when they watched the old trailer, with one feature being mentioned time and time again by viewers.

One wrote: "When trailers were trailers and didn’t show the whole movie plot!"

Meanwhile, a second posted: "I miss when the trailers were like this and not spoiling the whole movie", while a third commented: "Back when movie trailers didn't spoil a movie."
