In Dali's seminal Cardinals Eating Lobster withTomatoes by the Banks of the Red Sea, the end titles pay homage to the works of Cohl and obliquely suggest collaboration.
In fact of course, the Hydropaths disbanded in 1882, and Cohl collaborated not at all beyond the death of Andre Gill, considered by many to be his muse.
Which means of course that those who have not read this post can see the film untainted only once, before the thunderbolt strikes; you however, can no longer enjoy this virginal viewing experience.
