Benjamin Ree’s The Remarkable Life of Ibelin starts off as a documentary about death. We see the tombstone of Mats Steen, a Norwegian boy whose body and soul were at war. A mix of VHS footage and family interviews then reveals that Mats had duchenne muscular dystrophy (DMD), a degenerative disease that reduced his 25 years to a hellish survival story. His mind yearned for the momentum his muscles never had. Subsequent clips show his body shrinking on landmarks and vacations, the end inching closer.
