A film enthusiast left on Google this review which, with 2 stars and just a few lines, is fairly unremarkable.

However, it makes it possible to retrieve a crucial piece of information… which becomes very talkative once integrated into Google Maps.

It used to be easy to find Google reviews by simply searching the movie on Google, and looking at the reviews section.
However, Google removed that feature for movies some months ago (in late 2025). Now, all reviews are per-user on the brand new Google Profile website. But this website doesn’t have a searchbar to find the movie, and even with it, there’s no review attached to the movie.

We need to search using Google Search itself with the poor information we have: a blurred review with “anil kapoor” unblurred, and the movie’s title “Savi”.
We can even guess the word “of” before “anil kapoor”, that’ll populate our search.

Let’s try that with some Google Dorks:

1
site:profile.google.com "of anil kapoor" savi

Among the few results, one of them is from a profile named “Diret Disco”. On their profile, we can find their review of “Savi”:

Same review length, same word position, same rating, same relative time. That’s the one!

Now that we have the review profile, we need to find the corresponding Google Maps profile, that doesn’t use the same ID as the one we have on the link of the Google Review profile. Google Maps uses an all digit ID.
Opening the source code of the review page (CTRL+U) and searching (CTRL+F) for k4cxyig4 (the profile ID), we can find a script filling the reviews dynamically. In this script, we can find the digit ID associated to the profile:

1
data:[null,[[null,null,[[null,null,null,null,"102786079115098093662","k4cxyig4"...]]]]]

The digit ID is 102786079115098093662. From here, we can open our own Google Maps profile review page, and replacing the ID by this one, forming: https://www.google.fr/maps/contrib/102786079115098093662/reviews.

Now, we are searching for a picture. Heading to the “Pictures” tab of the profile, we can see multiple pictures. Sorting them by date allow us to find a review from a place named “Francium (Pvt) Ltd Bambalapitiya” with 3 pictures of a watch, on which we can see the steps and time!
