Gervase Duan "G.D." Spradlin, a character actor best known for playing authority figures in television and films, including 'The Godfather: Part II' and 'Apocalypse Now,' has died. He was 90.

The 'Los Angeles Times' reports that Spradlin died of natural causes at his cattle ranch in San Luis Obispo on Sunday.

Born in Oklahoma in 1920, Spradlin served in the Army Air Forces in China during World War II and worked as a lawyer before becoming rich as an independent oil producer.

He turned to acting in his 40s and used his real-life experience as an attorney, oilman and rancher to play men in charge.

Spradlin also directed John F. Kennedy's 1960 presidential campaign in Oklahoma and ran for mayor of Oklahoma City, unsuccessfully, in 1965.

(S02E21) If you were waiting all season long for an episode this power-packed, you finally got your heart's desire. You wanted action; you got it. Story line development? Check. More about Sarah and Chuck? Casey in the middle of everything? Guest stars? References to pop culture and old movies? Morgan's deepest dreams revealed? Yep. This was the episode for you. The penultimate Chuck for season two -- and hopefully not the next to last of all time -- was perhaps the best episode of the year.

For sheer dynamics, the team was not working together. Casey, who was promoted and thus became the colonel of the title, was put in the tough position of having to apprehend Chuck and Sarah. Since they all know each other so well, there was no advantage on either side, and Chuck's emotional appeal about finding his father seemed to have little effect on Casey.

(S02E20) Trust. Five little letters that represent so, so much. For Chuck, trust has been key to his agreeing to be the American government's good little intersect. He's gone along with all the dangerous assignments, put his life on the line, lied to his friends and family, and every step of the way, he's trusted that Casey and Sarah and the General are working for the country's best interest, and by extension, his best interest.

After convincing the General that the only way to keep Fulcrum from getting their own intersect, the one not in Chuck's head, was to steal back Orion before he succeeds in building another unit. The fact that Orion was also Steve Bartowski -- Chuck's primary objective, i.e. "get back dad" -- was evident. However, for appearances, he let the team believe that he believed saving the interset was the most important thing.
