The 1914 film, "A Thief Catcher," turned up in 2009 at an antiques sale in Taylor, Mich.
Film historian Paul Gierucki thought he was buying just another Keystone Studios comedy and didn't watch the 16mm print until last March.
Gierucki will introduce the film before it is shown Feb. 26 at White Concert Hall at Washburn University.
The focus of the rest of the festival will be "The First Academy Awards 1927-28." Organizers say there will be an authentic Academy Award statuette from 1928 on display for festival-goers to view.
Festival events are free, and the public is welcome.
