FRules at the time of the first three Academy Award ceremonies allowed for a performer to receive a single nomination for their work in more than one film. At the 1st ceremony, Emil Jannings won Best Actor for his work in two films and Janet Gaynor won Best Actress for her work in three films. Richard Barthelmess also received a nomination for two films at the 1st ceremony. At the 3rd ceremony, George Arliss, Maurice Chevalier, Ronald Colman, Greta Garbo and Norma Shearer all received a single nomination for their work in two films. This is why the Academy lists Colman and Garbo as three-time nominees and Shearer as a five-time nominee. Barthelmess, Arliss and Chevalier are one-time nominees, so do not feature in the above lists. No official reason was ever given as to why Arliss and Shearer were named Best Actor and Best Actress for only one of the two films for which they were listed.&lt;br&gt;
