* "Sith" refers to a group, not a movie. They're a faction of the Force-wielding dark side users in the Star Wars universe.
* Many Star Wars movies feature Sith characters. For example:
* Darth Vader (Anakin Skywalker) in Episodes III, IV, V, and VI
* Darth Maul in Episode I
* Count Dooku in Episodes II and III
* Darth Sidious (Palpatine) in Episodes I, II, III, VI, and IX
Let me know if you want to ask about a specific Sith character or a particular movie!
