Answer:
Special effects and action. 
Explanation:
American movies have frequently been described as action-packed and very fast-developing. This comparison is usually made with Latin American, European, and East Asian movies that tend to place more emphasis on character development than the average American movie. 
Recording and editing has also played an important role by speeding up the development of the films and allowing them to reach a climax defined by an adrenaline rush.

The correct answer is the last option: If you take away the suffix –n and the prefix un-, the root word is “know”.
Prefixes and suffixes are sets of letters that are added at the beginning (prefix) or end of a word (suffix). They are not words by themselves, but they do change the words' meanings or categories.
In this case, the root is know. The suffix -n is used to change the word's category from verb (know) to noun (known). While, the prefix un- is used to mean NOT. As a result the meaning of the word UNKOWN would be not known or familiar.
