After years of watching Matthew McConaughey waste his talent on mediocre movies (“Ghosts of Girlfriends Past”? Really?), it’s a pleasure to finally see him sink his teeth into a challenging role. In “Dallas Buyers Club”, he plays Ron Woodroof, the homophobic man who gets diagnosed with HIV and finds himself with just 30 days to live. In order to survive, he steals AZT (a drug used to delay the development of AIDS), and when that doesn’t work he travels to Mexico to try experimental treatment administered by a Dr. Vrass. Later on he meets a transsexual druggie (a terrific Jared Leto) and together they form a Dallas Buyers Club that gives away effective, non-approved medicines for AIDS patients. In many ways, the most important ingredient in “Dallas Buyers Club” is McConaughey. Without his movie-star charisma the film wouldn’t work nearly as well as it does. It is essential that we identify with his character and root for him as his body begins to waste away (he dropped 38 pounds for the role!). I hesitate to describe plot details any further, as I think audiences should experience the journey for themselves. What you do need to know is that the acting is top notch all the way. McConaughey, on a career roll, is magnificent. His deeply felt scenes with the standout leto hit you like a shot in the heart. It takes a supremely confident filmmaker to trust his content and actors. And in the hands of director Jean-Marc Valle, “Dallas Buyers Club” emerges as one of the best movies of 2013. Do not miss it.
