"Summer Lovin'" really had audiences having a blast in 1978 when the romantic musical comedy Grease hit theaters, starring an up-and-coming John Travolta and rising singer Olivia Newton-John.
The film was a huge success, and is still a major influence on many musicals to this day. When it came out, it made nearly $400 million at the box office and ended the year with the second best-selling soundtrack of 1978, falling behind Saturday Night Fever, another Travolta hit.
The film spawned one sequel with a completely new cast, as well as a live TV adaptation on Fox earlier this year.
Though John Travolta and Olivia Newton-John will always be the faces in our memories from Grease, the rest of the cast still went on to do a lot of work, many turning to the voice acting world. Let's take a look at the cast and see what they've been up to for almost four decades.
