Becky Gomez or Becky G, singer and actress has been cast as the Yellow Ranger for the Power Rangers reboot 2017 film. Names have not been officially released as of yet. There are rumors flying they will have the original names: Jason, Kimberly, Trini, Zack and Billy but another source says they will have new names. This weekend Power Rangers twitter says they will have the original names.
Naomi Scott will be pink and Dacre Montgomery will be red.
RJ Cyler as blue ranger and Ludi Lin as black ranger. I find them using the original names refreshing they changed the ethnicities. It would be an interesting take to see an Asian Zack, an African-American Billy (which we've seen with Noah in Megaforce and Ethan in Dino Thunder) and a Latina Trini.
As for the plot, I'm not believing anything until it is official or approved in some way by Saban or from a credible source.
