Around age 17, Brandis landed one of his best-known roles, as scientific prodigy Lucas Wolenczak in Steven Spielberg's futuristic science fiction series seaQuest DSV. The role propelled him into teen idol status.^[5] At the height of his popularity, Brandis received approximately 4,000 fan letters a week and had to be escorted onto the set of seaQuest DSV by three studio security guards because of the many female fans present.^[2] He voiced Mozenrath, an evil young sorcerer, in Disney's animated series Aladdin.^[6]

Brandis did not leave a suicide note.^[12] After his death, friends reported that he had been depressed about his extended career lull and was reportedly disappointed when his appearance in the 2002 war drama Hart's War—a role he hoped would revive his career—was significantly reduced in the film's final cut. Brandis began drinking heavily and said that he intended to kill himself.^[13]

In 2021, his father, Greg Brandis, noted that Jonathan was probably suffering from bipolar disorder. He told People, "[His death] wasn't due to the entertainment industry. I look back now, and in his 20s, he showed signs of manic depression. I hope that anyone suffering can go get help."^[14]
