AVClub: The postmodern practice of recording every aspect of your daily life for posterity certainly has its downsides, but it’s also what makes a movie like Gleason possible. The documentary follows the everyday routines of former pro football player Steve Gleason, from his days as a college linebacker through his career with the New Orleans Saints up until the present day. Only a brief portion of the film is devoted to Gleason’s moment of gridiron glory during the Saints’ highly symbolic comeback after Hurricane Katrina, though. Most of it is dedicated to Gleason’s struggle with ALS, also known as Lou Gehrig’s disease, a progressive neurodegenerative disease that gradually weakens the muscles, affecting a person’s ability to walk, talk, and eventually breathe. Gleason was diagnosed with ALS in 2011, and he was given two to five years to live.
