In "Novocaine", a lukewarm cross-genre flick which isn't dark comedy but which does have a tan, Martin plays a dentist who finds his successful but bland lifestyle somewhat like pulling teeth and murder follows. The principals turn in better performances than writer-director Adkins who steers this mildly entertaining flick schizophrenically through the genres and into some awkward situations especially the whole dental thing in the end. Worth a look if expectations are kept low.
