"How series deal with death"

My faith in The West Wing to do the right thing was bolstered by Sunday's (Jan. 8) terrific episode, which by eerie but satisfying happenstance focused on Leo's character as he prepared for a vice-presidential debate, ultimately exceeding everyone's (including his own) low expectations. In a special introduction, Martin Sheen praised his colleague and friend, noting that the best tribute to a character actor like John Spencer is the opportunity to watch and appreciate his final months of work.This "Running Mates" episode was one of Spencer's best in a long time, as he sparred with his handlers, most notably Kristin Chenoweth as perky Annabeth. "What my life has come to... " Leo growled as Annabeth literally tried to wipe the smirk off his face, forcing his lips into a scowl. "You seem to have graduated from cudgel to bludgeon," he snarled, albeit affectionately.
Even if (like me) you predicted that Leo was the one leaking news of his dreadful debate rehearsals to the blogosphere, it was great fun admiring his caginess.
And in the episode's most unnerving sequence, you couldn't help flinch when he was asked a question about his own medical condition. He turned it into an attack on Republican health care, starting with the blunt acknowledgment: "By an overwhelming percentage, the first warning symptom of a heart attack is death."
A more timid show might have squelched this sadly prophetic exchange. But I'm betting John Spencer would have relished the irony.
Just as Leo McGarry proved to be a formidable candidate to the end, so did John Spencer always deliver the goods, even when the show itself left a lot to be desired.
He'll be missed, for sure â€" but more important, thanks to episodes like this, he'll be remembered.

TV president Martin Sheen tugged at America's heartstrings on Sunday night when he paid a personal tribute to late The West Wing co-star John Spencer at the beginning of the new season of the political drama.The new season of the show will begin with Spencer's final episodes. The actor died of a heart attack on 16 December.
Sheen, who plays President Josh Bartlett on the hit show, took a moment to remember his pal, stating, "Good evening. On December 16 we lost our good friend and colleague John Spencer.
"Through our shock and grief, we can think of no more fitting memorial to this wonderful man, this extraordinary actor, than to share with you, beginning tonight, the last few months of his work here on The West Wing.
"Johnny, it seems we hardly knew you, we love you and we miss you."

At a press conference, Executive Producer John Wells said the mid-December death of series regular John Spencer briefly led to a discussion of whether it was appropriate to continue the series without him, and whether the three filmed episodes he was featured in prominently had to be re-shot."The conclusion we came to was John was so wonderful in the episodes that the best homage we could make to his contribution was to let people see the last days of his work," said Wells. "We did not change or edit a single thing."

Executive producer John Wells said there was a brief debate among producers about editing out some of the scenes Spencer filmed before his death."We decided to leave his marvelous acting work untouched," Wells said.
"If you knew John, I think he would have been upset with me if we had actually changed scenes. Like, 'What! You're cutting my scenes, kid? What are you doing that for?' "
