Only the most eagle-eyed viewers can spot mistakes in their favorite films and TV shows. But just how can a project on which countless hours and millions of dollars be released with errors in?! Read on to discover some of the biggest bloopers out there...

An almost unnoticeable mistake on ‘Pirates of the Caribbean: The Curse of the Black Pearl’ (2003) occurs in a scene where a man wearing a cowboy hat can be spotted in the background. Fans believe it must have been an extra or a crew member. He should have worn a pirate hat instead!

On ‘Gliding Over All’, the eighth episode of Season 5 of ‘Breaking Bad’, Jack Welker (Michael Bowen) tells his nephew Todd (Jesse Plemons) something about Osama bin Laden’s death. Viewers immediately noticed this was a mistake, as the episode takes place in 2007, and the Al-Qaeda leader died in 2011!

On episode 15 of Season Two of 'The Big Bang Theory', ‘The Maternal Capacitance’, Penny (Kaley Cuoco) has a conversation with Beverley (Christine Baranski), who is the mother of Leonard (Johnny Gaelecki). During their chat, as she is speaking about her father, Penny says: "My mom could have just said, 'Bob, get over it; she's a girl, move on.'" For almost two entire seasons fans thought that Penny’s father’s name was Bob. But that was not the case when in episode 9 of Season Four, ‘The Boyfriend Complexity’, as Penny's dad is introduced to the audience as Wyatt.

In 'American Sniper' (2014), Bradley Cooper plays Chris, a veteran who tries to readjust to normal life after spending time in Iraq. Despite earning countless plaudits, in one of the scenes, Bradley’s character is holding a baby in his arms which couldn't look anymore fake! Cooper himself recalled this hilarious incident on the set of ‘The Ellen DeGeneres Show’, saying: "I couldn't believe that we were working with a plastic baby... I was just like, this is nuts."

Quentin Tarantino's 1994 masterpiece 'Pulp Fiction’, featured an all-star cast which included John Travolta, Samuel L. Jackson, Bruce Willis, Uma Thurman and more. Travolta and Jackson play gangsters Vincent and Jules and in one scene they go to an apartment to retrieve a briefcase for their boss. As they enter the room, bullet holes can be seen in a wall in the background. The only problem is that the pair hadn't fired their guns yet!

Some scenes of ‘Spider-Man: Far From Home’ (2019) take place in the Italian city of Venice. In one of them, a group of students get on a bus. Fun fact: buses and motor vehicles are not allowed in the city at all.

In episode 13 of Season Six of ‘The Simpsons’, titled ‘And Maggie Makes Three,’ Marge tells Homer that she is pregnant, expecting the youngest of their three children, Maggie. One problem, there is a picture of Maggie hanging on the wall in the background.

Another one of Quentin Tarantino’s films is ‘Once Upon a Time in Hollywood’ (2019), which stars Leonardo DiCaprio as fading actor Rick Dalton and Brad Pitt as his stuntman Cliff Booth. In one scene, we get to see a Starbucks, the famous coffee chain that was founded in 1971. Trouble is that the drama is set in 1969.

‘Game of Thrones’ has been one of the most successful series of recent years, but that does not mean that the show doesn’t have any mistakes. During one scene in the final season, fans noticed something strange in the background… a Starbucks cup! Series creator David Benioff addressed the issue, admitting he could see the funny side of a coffee being on display in a medieval fantasy series. He said: "At first I couldn't believe it, and then it was an embarrassment because, 'How did we not see this coffee cup in the middle of the shot?' And then eventually it was just funny. This one is just a mistake, and it's kind of funny to us now."

Starring Leonardo DiCaprio and Kate Winslet and directed by James Cameron, disaster epic ‘Titanic’ hit theatres in 1997 and was a MAJOR box office success. One of the film’s most iconic scenes is when Kate’s character Rose undresses, so Leonardo’s alter ego Jack can paint her. Jack then asks her to go “over by the bed,” only to correct himself by asking her to go “to the couch.” This “fictional” mistake was, in fact, a real-life mistake by Leonardo DiCaprio, but the crew decided to leave the scene like that, as it seemed to be more genuine as it showed he was nervous.
