Can you iden­ti­fy the man in this pic­ture? The archivists at Lost Films hope you can. The image is tak­en from footage of a vin­tage film that no one has been able to iden­ti­fy. Accord­ing to the descrip­tion that goes with the still, all we know now is that this odd­ly-dressed  char­ac­ter is an escaped con­vict named “Hem Lock.” The movie is prob­a­bly Amer­i­can, and it was most like­ly shot some­where around 1923. If you think you can add some more infor­ma­tion, it’s time for you to sign up.

More than 80 per­cent of silent films and a high per­cent­age of old sound films have been lost or are now unac­count­ed for. Lost Films is a col­lab­o­ra­tive effort among film soci­eties in Ger­many, France, Poland, New Zealand, and sev­er­al oth­er coun­tries to help iden­ti­fy and locate some 3,500 lost or miss­ing films through crowd­sourc­ing. Any­one can become a mem­ber and then upload clips and images from “mys­tery movies” to the site, and also com­ment on the as-yet-unti­tled stills and images that have already been uploaded. The site also con­tains a heart­en­ing list of films that have been recent­ly been recov­ered.

The project is fund­ed by the Ger­man Fed­er­al Cul­tur­al Asso­ci­a­tion.

Be sure to find many silent and ear­ly sound movies (among oth­er things) in our col­lec­tion of Free Movies Online.

Lars von Tri­er stepped on the third rail Wednes­day when he called him­self a Nazi and Hitler sym­pa­thiz­er in jest. The joke did­n’t go over so well, and, his apolo­gies (some­times sound­ing sin­cere, some­times not so much) did­n’t win peo­ple over. Today, Cannes offi­cials took an unprece­dent­ed step, declar­ing him per­sona non gra­ta at the fes­ti­val. This marks the first time Cannes has exiled a direc­tor in its 64 year his­to­ry. What will Lars do next? The prova­ca­teur sug­gests that he will return to his native Den­mark and shoot porn films:

I want to be sur­round­ed by porn peo­ple who love me for what I am, who say, ‘Where do you want the erec­tion, where do you want the pen­e­tra­tion.’ Where it’s not com­pli­cat­ed. There would­n’t be a porn star run­ning out there say­ing ‘Lars said this or Lars said that.’

He also might want to add hir­ing a few good han­dlers to the to-do list. Mean­while, if you’re look­ing for a few clas­sic Dan­ish films, we have Vampyr and La Pas­sion de Jeanne d’Arc, both by Carl Theodor Drey­er, in our col­lec­tion of Free Movies Online.
