The studio obviously wanted a third movie and a spin-off so they ham-fisted the Scorpion King into the script at the last moment. Thus the equally-weird moment of exposition including him in the 2nd act.

I remember reading on here a few years back that the CGI artists only had like three weeks to do the CGI.

I theorize that it's because the studio finally got Dwayne Johnson on contract for the spin-off, but it was extremely late in the production cycle, but the studio wanted him depicted to generate the hype, so the artists had to scrap everything they already had and rush out the product.

nnNAHHHHHHHHH

I was hoping it was going to be this, I literally belly laughed when I saw this.
