I was at a dinner with Dennis Christopher a few years ago, and I got to ask him the question that has bugged me for decades. How many takes to scoop up the notebook?
Turned out that it was one take, in fact the rehearsal for the real take, but Dennis picked it up perfectly on the first try, and the director just kept the scene rolling.
You might be disappointed to learn that Dennis is gay and smokes cigarettes. Says he still has the Masi, but it hangs on the wall.
The chainring blooper has been common knowledge since the first time I saw the film.
