"It is with a grieving heart that I let you know of the death of 19-year-old Matthew Mindler from Hellertown, Pennsylvania, a first-year student at Millersville University. Our thoughts of comfort and peace are with his friends and family during this difficult time," an email from the university reads.
"Our Idiot Brother," starred Rudd, Elizabeth Banks and Zooey Deschanel. Mindler played River, the son of Liz (Emily Mortimer) and Dylan (Steve Coogan) "who is heavily controlled by his parents and therefore unable to express himself," according to Variety.
He's also credited for a role on the long-running soap opera "As The World Turns," according to IMDb.
