Crime-thriller "Parker" -- pairing Jason Statham with Jennifer Lopez -- is likewise D.O.A. as a glut of R-rated films make life tough at the domestic box office... Paramount and MGM's action-comedy Hansel & Gretel: Witch Hunters topped the weekend chart with a $19 million opening but underperformed despite star Jeremy Renner and the upcharge for a 3D ticket. Hansel & Gretel, like other films, took a big hit Friday night because of a major snowstorm stretching from the Midwest to the Mid-Atlantic.
