This movie is sequel to 1996 film Mission: Impossible]. Movies are casted by actors where an actor has specific role (Example: MI 2 is starred (i.e., main character) by Tom Cruise) and an actor is identified by id, firstname, lastname and gender. A movie might have multiple genres (Example: MI 2 is characterized by three genres: Action | Adventure | Thriller). A director who directs a movie is identified by id, firstname and lastname. We assume a movie can have at-most one director. (Example: John Woo is the director of MI 2 and he also directed well-known movies like 'A better tomorrow', 'Red Cliff', 'Hard Boilded', 'Face/Off'] i) Draw ER diagram with proper notation. (7)
