Wonder Woman (2017)
Since this movie is a superhero movie, it's inherently silly, ergo it's riffable. And I would like Mary Jo Pehl and Bridget Jones Nelson to do the riffing because the Superhero is an iconic woman superhero and the movie was directed by a woman, meaning it just wouldn't feel right if Mike, Kevin, and Bill riffed it. Besides, you riff Blockbusters all the time, right? It would be amazing to see (or hear, rather) Mary Jo & Bridget riff their first Superhero blockbuster.

This should be riffed, but I think Mike and the guys should do it. I've become accustomed to their voices. :)
