Welcome Back Kotter star John Travolta headlines the made-for-TV Boy in the Plastic Bubble. Douglas Day Stewart's fact-based teleplay casts Travolta as Tod Lubitsch, a teenager who was born without disease immunities. Tod is forced to live out his life in incubator conditions; whenever he vetnures into the outdoors, he must be encased in a huge plastic bubble. When he falls in love with Gina Biggs (Glynnis O'Connor), Tod must decide between staying safe and following his heart, which would mean facing near-certain death. Diana Hyland won an Emmy for her portrayal of Travolta's mother. Incidentally, Hyland and Travolta became real-life lovers, a relationship that was tragically terminated when the actress died of cancer. Boy in the Plastic Bubble was first telecast November 12, 1976.
