Grease is one of the classic movies that everyone has probably seen. Most can sing some of the more popular songs from the movie such as 'You’re the one that I want' and 'Summer Nights'. Grease, starring Olivia Newton John and John Travolta, is a pretty good movie. It's not like on my list of favorites, but it's pretty high up there. Maybe I have just seen it too many times because they do always seem to play it a lot on TV. Anyways it's a good movie filled with great catchy songs, dancing, romance, and laughter. There aren't any extras on the DVD unless you get the special edition which includes 15-minute long excerpts from the "25th Anniversary DVD Launch Party" and 11 deleted/extended scenes among other things. There are a lot of great extras that you will enjoy if you are a fan of this movie.
