A brief, passionate encounter between an attractive woman and - a tennis ball machine. On the face of it, this 1975 short film is a breezy spoof on the tennis craze. But "The Tennis Lesson" also serves as a commentary on the machine age, in which human beings increasingly depend on technology to meet all their needs. Produced and directed by Steve Karp and executive producer Tom Gallagher.
