Colbert was very particular about how she appeared on-screen, and believed her face was difficult to light and photograph. She insisted on having the right side of her face away from the camera because of a small bump from a broken nose as a child. This sometimes required movie sets to be redesigned. During the filming of "Tovarich" (1937), director Anatole Litvak dismissed one of her favored cameramen. After seeing the rushes filmed by his replacement, Colbert refused to continue. She insisted on hiring her own cameraman, and offered to waive her salary if the film went over budget as a result. Gary Cooper was terrified at the prospect of working with Colbert in his first comedy, "Bluebeard's Eighth Wife" (1938), considering Colbert an expert in the genre.
