Enigmatic Austin-based director Terrence Malick’s recent Cannes Film Festival Palme d’Or winning drama The Tree of Life is new on DVD this week. Set largely in the 1950s, the film follows a stern Brad Pitt and his caring wife Jessica Chastain as they raise three boys to face the challenges and mysteries of the world around them. Sean Penn plays Pitt’s eldest son, all grown up and wrestling with the reasons for his father’s tough love and the meaning of life, even 40 years later. Hunter McCracken and Fiona Shaw co-star. Rated PG-13.
