Another update via Ed Boon's Twitter! Now, he's posted a photograph of Richard Divizio in his Kano garb from Mortal Kombat 3. Also visible: Ed Boon himself in the foreground. From the Boonmeister directly.

Here is (the great) Rich Divizio doing the motions for Kano's fatality in MK3. Old school style blue screen!

Note: In the recent past, Ed has also behind similar photos of the Goro and Sheeva models, from MK1 and MK3, respectively.
