'Grease' somewhat typecast Newton-John, and she struggled to pick up major acting roles despite the box office success of the film. She kept going with the music, though, and has so far released another eighteen studio albums, with the most recent being a Christmas album issued in 2016.
Now 70 years old, it would be fair to say that she is better known for being herself than anything else. She's had many television roles since her 'Grease' days, but most of them have either been cameos as herself, or appearances in which she's not been required to act. She's also been a talent show judge for television, sitting in the chair for the successful 'Dancing with the Stars' series. Perhaps inspired by her youth in the countryside of Australia, Newton-John has become an advocate for environmental issues, which she's invested a great deal of her own time and money into.
