Well on January 31, 2016 Julianne Hough will be cast as Sandy. She will be 27. A woman well known to many, many people and all Dancing With The Stars viewers will play a high schooler. That's really believable. I am being ironic with last sentence. One thing to cast an unknown in their 20s to play a hogh schooler but someone this high profile? No. This article speculates who will play opposite her, oh just hire Mark Ballas just to do a comp,ete DWTS connection and Maksim's brother to play the Rizzo's bf. Greased Lightning would.be interesting. I do hope they cast Olivia.Newton John as the principal just to connect with the movie. Could be worse then Peter Pan.
