"

Lewis screened Spielberg's early film Amblin' and told his students, "That's what filmmaking is all about."[7] The class covered all topics related to filmmaking, including pre and post production, marketing and distribution and filming comedy with rhythm and timing.[8] His 1971 book The Total Film Maker, was based on 480 hours of his class lectures.[9] Lewis also traveled to medical schools for seminars on laughter and healing with Dr. Clifford Kuhn and also did corporate and college lectures, motivational speaking and promoted the pain-treatment company Medtronic.[citation needed]
