They're systematic, hydromatic, ultramatic...why, they're Grease-d lightning!

We've finally seen the first images of the cast of Fox's Grease: Live in costume, and these looks are as on point as the gang doing the hand jive! Fox released the first photos of the cast Monday, with Julianne Hough as Sandy, Vanessa Hudgens as Rizzo and Aaron Tveit as the hunky Danny (and we cannot argue with that casting).

Take a look:
