First a Broadway show, then a film, the 1970s musical “Grease” has now become a live television special, starring Julianne Hough and Aaron Tveit. Fox aired this latest adaptation Sunday night.
Once you rent a movie, you get 30 days to start watching it, and then 48 hours to finish once you've pressed play. If you buy "Grease," you can stream it whenever you'd like with no restrictions.
