The film's being distributed by Verve Pictures, who have some basic info about it up on their site.
Alpha Male is a story of family life: of bad parenting, family politics, repressed emotions, great love and devastating loss. When Jim Ferris dies, leaving behind a family fractured by his absence, his young son Jack is prematurely burdened with the responsibility of looking after the family. When Jim’s widow Alice meets and marries a new man, a firm wedge comes between Jack and the rest of the family. It is another eleven years before the rifts can even begin to heal as they all come together again for Jack’s 21st birthday weekend.
In case you missed it, earlier we posted a video clip of the movie. Warning, it seems to be from the end of the film.
