I have seen this awesome gif of Wonder Woman lots of times, but I don't know its origin.
So far Gal Galot has appeared as Wonder Woman only in 3 movies viz. Batman v Superman, Wonder Woman, Justice League. And, as far as I recalled, she was always in serious scenes in all these movies. When could she go for this cheerful spin?
There are other possibilities I can imagine:
CGI. Hard to believe because of cost, but you can never underestimate fans.
Gal Galot's home made video.
Fun video shoot on movie set. If yes, which movie set?
