Elephant Walk, released in 1953 or 1954?

But IMDb may have a source for the edit

Don't think it's possible for them to have a source for the edit. Likely someone wanted to change the title year to the production year, and did that by editing the year on first listed release date without any valid source or no source at all, and it was approved incorrectly. Like how they approved a 2017->1917 change on the 25 June release date of this title recently, which I fixed. Someone wanted to change title year, and changed only the year on existing release date for "restored version", but that specific date was for 2017 restored version release, it's even in the attributes, so a year change from 2017 to 1917 on that specific item shouldn't have been accepted because no source could be provided for it.

Anyway a similar case here, someone wanted to change title year and did that by inaccurately modifying an existing correct date.

AFI has a lot of details about its production and release. History section talks about production problems mid-Mar 1953, also confirmed by reports such as:

Oh Michelle already corrected it while I was writing this :)

@Michelle 

If it was a premiere, you should include attributes (New York City, New York) (premiere)

Hi Peter_pbn -

Yes, I missed the attributes, thanks for the reminder!  They have now been included on the existing Release date for the title.

Cheers!
