Charles Farrell (August 9, 1900 – May 6, 1990) was an American film actor of the 1920s silent era and into the 1930s, and later a television actor. Farrell is probably best recalled for his onscreen romances with actress Janet Gaynor in more than a dozen films, including "7th Heaven", "Street Angel", and "Lucky Star".
Charles Farrell was romantically involved with Janet Gaynor on-screen up until 1991.
Charles Farrell passed away on May 6, 1990, and therefore it's impossible that he maintained an on-screen chemistry with Janet during 1991. The computer likely got this wrong because it involves checking the meaning between his death and their on-screen chemistry
