With 'Transformers: Dark of the Moon' claiming the third biggest global opening of all time over the weekend, one eagle-eyed YouTube user has spotted something that has set the internet abuzz.
The video suggests, and successfully demonstrates, striking similarities between the latest 'Transformers' film and 2005 movie 'The Island', which starred Ewan McGregor and Scarlett Johansson and is also directed by Bay.
Actually it appears to be even more brazen than that. Not only are the clips similar, they seem to use identical footage but with added robots for the latest movie.
The stretch of road used in the car chases is apparently the same, and so are the vehicles involved. Most damning is the slow-motion carnage that the YouTube uploader (a Venezuelan filmmaker called Jermaín Odremán) has highlighted. There is little doubt left that this is the same footage recycled.
And it's not the first time this has happened either. Another clip, also on YouTube, shows footage from 'Pearl Harbor' being recycled in one of the earlier 'Transformers' films.
'Transformers: Dark of the Moon' opened on Wednesday and has now grossed over £230 million internationally. It's also on target to break 4 July records in the US, and could well reach £110 million over the American holiday.
The numbers would suggest more in the franchise, but both the film's star Shia LaBeouf and director Michael Bay have said this will be their final outing.
Still, who is to say Bay won't be returning to the series to use some of the footage for his next project?
