A Modern Thelma The New York Clipper repeatedly referred to a five-reel Fox film which was released on April 17, 1916 as starring Theda Bara. Everything was correct except that Theda Bara was not in it. Vivian Martin was the title character. Not sure why this error was repeated in multiple issues. The fact that its release date was so close to another Theda Bara film should have caused some editor to raise a question. I don't think the error was made just because this film also starred Harry Hilliard, who played with Theda Bara in Romeo and Juliet.
I know I have other titles which somehow got pinned to Theda Bara...tentative titles, movies that never got made or movies made which had nothing to do with her.
