In 2001, Roman Coppola made a film called CQ. Two years later, Bernardo Bertolucci made a film called The Dreamers. Both filmmakers shot a scene at the same location in Paris. Coincidentally, the same blue bicycle appears in both shots. In 2005, I asked some friends headed for Paris to see if the bike was still there. It was. In 2006, my girlfriend and I visited the location. The blue bicycle was still there! We talked to a nice man who told us that the bicycle was a sort of informal monument, so we decided not to steal it. I don't know if the bike is still there now. If you know, please take a picture of it for me. Update: Thanks to Cecile Edelist, we know that, as of October 7, 2009, the blue bicycle is still there! (less info)
