There are no listed releases of Amazon in either Region 1 US or Region 2 UK; in fact Amazon.com only lists our Region 4 box set release. There is a Region 2 French version that is listed as including filmographies, publicity spots and interviews, but details are sketchy. That release is listed as having English subtitles, but it is unclear if they are for the extras as well as the feature. With the good value of our release, including 3 other films, it is to be preferred.
I also cannot find an equivalent Belmondo collection listed on sales sites. The only thing close is a Region 2 UK collection that includes Breathless, Pierrot Le Fou, Le Professional, Stavisky and A Double Tour.
