Faramir

Faramir is a character from Lord of the Rings. He is the younger brother of Boromir, and son of Denethor, Steward of Gondor, and Finduilas of Dol Amroth.

He is the leader of the Ithilien Rangers, and is said to be descended from quite a pure strain of Numenorean blood.

Bookverse
In bookverse, Faramir is a gentle-hearted man who, while renowned as a warrior, is also known for his wisdom. He offers help to Frodo and Sam almost unconditionally on learning of their quest, and even dispenses mercy to Gollum. He turns down the opportunity to claim the One Ring, claiming that he would not take it "even if [he] found it by the wayside".

Movieverse
Here, Faramir is made into rather a jerk at first. Instead of politely questioning the Hobbits, he immediately has them captured for interrogation. He also has Gollum beaten up, threatens to take the Ring from Frodo, and hauls all three prisoners to Osgiliath to send them to Denethor. After the Nazgul attack the city, however, Faramir reverts to book-verse and lets them go.
