This video is great because it captures the magic of late 1970s Hollywood, where I imagine parties like this were thrown at the end of every day of shooting. The production seems sort of amateurish, this is after all very early HBO, but the reporter comes out of the gate with a heck of a question. “What is the purpose of this party?” Olivia Newton John seems thrown by the question. After trying a few answers, she comes up with the correct answer, “she just likes to party”.
After Olivia he gets to talk to Gene Kelly who reveals why he is finally getting back into films after a long hiatus.
