The actor-writer-director, who was part of comedic gems like "Ghosbusters," "Stripes" and "Groundhog Day," died of a rare blood-vessel ailment. The Chicago Tribune obituary is here. Ramis got the swaggering smart-alecky attitude that fueled comedy in the '70s and '80s, especially the work of Ramis's frequent collaborator, Bill Murray. But where it's temptiong to give Murray, who has a great gift for improvisation, the bulk of the credit, there were times when the words mattered, and the words were often Ramis's. Look at the near-poetic construction of the scene above, from "Groundhog Day," screenplay by Ramis. And look at how Murray is respectiing the words, adapting his tone to the little verbal shifts.
