Well, looks like Clara’s 1923 film Maytime is on the National Film Preservation Website!
Maytime was discovered in 2009 at the New Zealand Film Archive (among about 75 other silent films). The film was preserved at the Colorlab Corporation, supervised by the Library of Congress and funded by David Stenn.
Clara plays the supporting role of Alice Tremaine, a friend of Ottilie van Zandt (Ethel Shannon) who sports fashionable dark-laced gloves. Maytime was one of Clara’s earliest roles (her fifth film, in fact), and her first film for Schulberg. The final reels are missing, alas, but at least we get to see nearly an hour of one of Clara’s previously lost films! Also, keep an eye out for Martha Mattox as Mathilda – you might recognize her from 1927’s The Cat and the Canary!
