In a new documentary titled "Super/Man: The Christopher Reeve Story," which premiered at the Sundance Film Festival, the close friendship between Christopher Reeve and Robin Williams takes center stage. According to actress Glenn Close, if Reeve had not passed away, Williams might still be alive today.

Glenn Close, who called both Reeve and Williams friends, expressed her belief in the documentary that the late comedian's life could have been saved if Reeve were still alive. Reeve, best known for his portrayal of Superman, tragically died in 2004 due to a cardiac arrest, at the age of 52. In 1995, he was left paralyzed after a horseback riding accident.

The documentary reveals that Williams and Reeve had forged a deep bond during their time as roommates at New York's Juilliard School before their rise to fame. This bond became even stronger following Reeve's life-altering spinal cord injury.

Williams, who starred in iconic films such as "Mrs. Doubtfire," threw an annual party for Reeve on the anniversary of his accident, showcasing their lasting friendship and support for one another. Close had previously shared her observations of their camaraderie during the filming of "The World According to Garp" in 1982, where Reeve would whisk Williams away for weekends in his own plane.

According to Close, the bond between Williams and Reeve was legendary and served as a source of strength for both of them. She firmly believes that if Reeve had survived, Williams would have as well. Their friendship was described as a "life-giving force" that sustained them through the fast-paced and extraordinary life of fame in the entertainment industry.

Williams, who tragically died by suicide in 2014, was diagnosed with Lewy body dementia only after his death. The autopsy revealed that there were no illegal drugs or alcohol in his system. Lewy body dementia, the second most common type of dementia, affects brain regions responsible for thinking, memory, and movement.

Glenn Close's sentiments shed light on the impact of strong friendships and support networks, emphasizing the potential influence they can have on mental health and well-being. The documentary serves as a reminder of the lasting impact that individuals can have on each other's lives, even long after they are gone.
