The sci-fi film, which also features Amy Adams and Jeremy Rener, is all set to hit theatres in India this Friday.
Whitaker plays Colonel Weber in "Arrival" and Denis said the actor has the toughest part in the movie.
"We all know he is one of the best actors living today. He is a master, and I saw that, because he had the toughest part on this movie. His character Colonel Weber was difficultly written, because he is in scenes as an obstacle, as an abrasive character," Denis said in a statement.
