I first saw Gainsbourg back in the spring of 2010 when I was part of the jury for COL-COA. I liked it then, and I liked it again when I re-watched it this week in a slightly shorter version. (The original was 130 minutes long; the new cut is 122 minutes.) I couldn't tell you what was taken out, but the film's overall impact feels the same: Eric Elmosnino is quite good in it as Serge Gainsbourg, but the biopic as a whole is only so-so. My review is up at The Projector for you perusing.
