The 50 worst movie mistakes you never noticed... until now

30. Who ordered the goat?  

The movie: Jurassic Park (1993) 

The mistake: During the film’s unforgettable T-Rex scene, the crew forgot one thing – one second the stripped goat’s leg is on top of the car carrying the kids, and the next second it’s gone completely.  

How noticeable is it? You’re probably more concerned about impending death-by-T-Rex to really worry about where the goat’s leg went. 

29. Spidey's crafting skills 

The movie: Spider-Man (2002) 

The mistake: Peter Parker (Tobey Maguire) tries out his new Spidey powers in his bedroom and smashes a lamp using his web-slinger. Moments later, we see him walk past a bookcase that still has the intact lamp on it.  

How noticeable is it? Very. That’s a really distinctive lamp, isn’t it? 

28. Popping out 

The movie: National Lampoon's European Vacation (1985) 

The mistake: Audrey Griswold (Dana Hill) has a dream that she’s eaten so much that she swells up considerably. Only the legitimacy of the scene is somewhat questioned when her green, inflatable fat suit shows through the parting in her top.  

How noticeable is it? Well, it’s just right there, isn’t it? Unavoidable. 

27. Slip of the tongue 

The movie: Charlie's Angels (2000) 

The mistake: Dylan (Drew Barrymore) and Alex (Lucy Liu) are going up against Crispin Glover’s hair-sniffing bad guy, when Dylan swings Alex round to kick him. Except when Barrymore goes to grab Liu, you can clearly see that she shouts “Lucy” instead of “Alex”.  

How noticeable is it?  If you’re any good at lip-reading, this one’s a corker. 

26. Wardrobe malfunction 

The movie: Harry Potter and the Order of the Phoenix (2007) 

The mistake: Harry Potter (Daniel Radcliffe) is having a nightmare about the Department of Mysteries, and we clearly see he’s wearing a pale blue crew neck T-shirt. When he awakens from his dream, he’s suddenly wearing a buttoned Henley T-shirt.  

How noticeable is it? You’ll probably be too weirded out by how ridiculously sweaty Harry is to notice the T-shirt switcheroo. 

25. Weightlifting 

The movie: The Day The Earth Stood Still (1951) 

The mistake: During the scene in which robot Gort picks up Helen (Patricia Neal) in order to transport her onto the spaceship, you can clearly see hoist wires behind her shoulders. Just how heavy was Patricia Neal?  

How noticeable is it? The film’s in black and white, but the wires stand out quite prominently against the grey background. 

24. Don't it make your blue eyes green? 

The movie: The Lion King (1994) 

The mistake: Throughout the film, Nala’s eyes change frequently from blue to green. Did they just run out of a certain colour of paint?    

How noticeable is it? Kiddies probably won’t notice as much, but we grown-ups like our eye colours to be consistent. 

23. Flames on, flames off 

The movie: Monty Python and the Holy Grail (1975) 

The mistake: Watch the campfire closely during the scene in which King Arthur fights the Black Knight. You’ll notice that the fire goes from lit to unlit and back again numerous times.  

How noticeable is it? Depends how much you like campfires. I mean, there is an armless knight wandering about in the foreground that's quite eye-catching. 

22. The gross cup switch-up 

The movie: American Pie (1999) 

The mistake: Stifler (Seann William Scott) is chatting in the bedroom with a lady he’s taken a fancy to. Meanwhile, the lady in question’s cup keeps changing from blue to clear depending on the shot.  

How noticeable is it? Considering that cup’s got something nasty in, it’s likely you’ve been staring at it throughout the entire scene. 

21. Real steel trees 

The movie: Chinatown (1975) 

The mistake:  During the scene in which Gittes (Jack Nicholson) visits the orange grove, you can clearly see a steel cushion has been wrapped around the tree that he crashes his car into.  

How noticeable is it? Well, it’s a big, shiny metal plate on a tree.
