A number of naïve individuals have caused a storm on the social media website Twitter by revealing that they had no idea that James Cameron’s record-breaking film ‘Titanic’ was based on a true story.

The Huffington Post was the first to notice the trend and compiled a gallery of users and their uninformed postings.

Twitter user @boring_as_heck retweeted some choice remarks such as “The titanic was real holy sh*t im never gooing on a cruise” and “Guys, the Titanic was real! #mindblown”.

Ironically, this week marks the 100th anniversary of the sinking of the Titanic which killed 1,514 people when it hit an iceberg during the maiden voyage from Southampton to New York.

The blockbuster movie, which stars Leonardo DiCaprio and Kate Winslet as ill-fated lovers who meet on the doomed ship, has been re-released in 3D to mark the centenary.

Read on and prepare to have YOUR #mindblown.
