In Italy, in her early films, most notably the multi-Oscar winner It Happened One Night (1934), she was dubbed by Nella Maria Bonora. Unlike other prominent Hollywood actresses, Colbert didn`t have an `official Italian voice`: She was often dubbed by Giovanna Scotto and Lidia Simoneschi but Marcella Rovena, Andreina Pagnani, Tina Lattanzi and Lia Orlandini lent their voice to her at some point as well.
She was so convinced that she would lose the Oscar competition in 1935 to write-in nominee Bette Davis, that she decided not to attend the awards ceremony. When she, contrary to her belief, won that year for her performance in It Happened One Night (1934) she was summoned from a train station to pick up her Oscar.
The vast majority of movie shots taken of Claudette Colbert were of her left profile. She considered her left side to be her best and only rarely allowed full face or right profile shots; an injury to her nose had created a bump on the right. Once an entire set had to be rebuilt so she wouldn`t have to show her right side; thus dubbing her "the dark side of the moon".
