Hints: In this case, it might be best to first check in the table is in 1NF, and then put the table into 1NF before trying to list the functional dependencies. To find the functional dependencies, ask yourself, if I know a value in this column (or these columns) do I logically know the values in the other columns (examples: If I know the movie, would I always know the rating? If I knew the Theater and the Movie would I know the Showtime?, etc.). There are two functional dependencies.
