When attaching to concrete, I suggest you pre-drill your holes using a hammer drill and a masonry drill bit. Use a smaller screw gun to attach masonry bolts/screws. Then, HAND turn the bolts (with a screw driver... the old fashioned way) for the last few turns.
Oh, and I like the movie. Especially the part with the girl. She's cute.
