The 8-minute version in colour that everybody seems to be watching is in fact the 1902 version. The 1907 version was also in colour and is, fairly obviously, much the same story but we dot have it and it was twice as long as this 1902 film. It is unlikely, if ever it does re-emerge, that a film of 1907 is going to look that similar to a film made in 1902. Five years at this period was a long time....
