A feel-good odyssey in the milieu of a Mark Twain tale, Tyler Nilson and Michael Schwartz’s Peanut Butter Falcon (B+) wins over cynics with career-best performances from two young actors and an introduction to another indelible character plus an easygoing and authentic sense of human adventure. After escaping a residential nursing home to pursue his dream of becoming a pro wrestler, a man who has Down syndrome (joyously played by Zack Gottsagen) befriends an outlaw (Shia LaBeouf) who becomes his coach and ally. Dakota Johnson is the counselor on the hunt through North Carolina’s Outer Banks for the coastal castaways. Through boat chases and Baptisms, gun fights and hideaways, the human bonds become increasingly heartfelt. The final reel sputters a bit after already securing the glory of its fabulous fable. Familiar faces abound, including Bruce Dern, Thomas Haden Church and John Hawkes in supporting roles. The film is sweet without becoming saccharine, and the characters stick to the roof of your soul.
