This is a relatively new term used in screenwriting circles. It’s a hybrid between high concept and low concept in many respects. A grounded film is firm rooted in reality, although the fantasy elements are vital. The ideas need to be big enough to be called high concept, but the characters must also be well drawn out. Think of it as HIGH CONCEPT DRAMA. The 2012 sci-fi film LOOPER is a good example of grounded execution.
