Writer/director/editor/cinematographer/caterer (just kidding about that last one) Robert Rodriguez’s “El Mariachi Trilogy” (“El Mariachi”/”Desperado”/”Once Upon a Time in Mexico”) finally make it to Blu-ray with excellent transfers, the original bonus features and a fun self-editing option called “The Cutting Room” for the viewer.

Those looking for a funny and gory romp through well-treaded territory need not look further than the 3-D Blu-ray release of “Piranha 3-D.” Director Alexandre Aja (“High Tension”) understands what his audience is looking for with a sleek, gruesome, nudity-filled horror-comedy that makes excellent use of 3-D technology. In addition, the disc contains a plethora of worthwhile bonus features, if the viewer is so inclined.
