In Sony's attempt to promote a trailer for the film Khali the Killer on YouTube, it made an incredible mistake that it was too late to realize. Instead of the trailer, it accidentally uploaded the entire film.

Khali the killer is a dramatic film that, judging from its trailer (the correct one this time), is influenced by 70s films. It was released on DVD in 2017, but there hasn't been a theatrical release yet, and it's also not available on any online streaming service. In any case, the film has suddenly appeared on Youtube!
The 90 - minute film has since been removed, although it remained available for several hours. A Reddit thread mocking Sony's mistake garnered a lot of attention, garnering over 31,000 upvotes.
“Another trailer that shows the entire plot of the movie..” one user quipped in a comment on the Reddit thread, garnering more than 15,000 Upvotes. Other users believe it was a deliberate move by Sony to draw attention to a movie that ultimately doesn’t deserve it. This is a tactic don’t believe Sony followed, as it is still trying to make amends for the 2014 hack that exposed the personal information of thousands of its employees.
The process for posting a video on the platform leaves room for error. It is most likely that the work was undertaken by someone with little experience on the YouTube platform. Sony has not made any public statement on the matter.
