I’m a little late stumbling onto this, it seems:
I’m not a smoker myself, but I love this poem for how it captures the wistful fondness we may feel for old vices long sworn off; and I love what the animator does with it: the smoke becoming as much a metaphor visually as it is in the text, the video itself a second poem.
This is part of a series called “Billy Collins: Action Poetry” — created a few years ago by JWT-NY for the Sundance Channel — which features readings by the former U.S. Poet Laureate (and one of my favorite poets) as brought to life by various animators. You can see the rest on YouTube, or in higher quality here.
