sped up because of a challenge Hawks took upon himself to break the record for the fastest dialogue on screen, at the time held by The Front Page. Hawks arranged a showing for newsmen of the two films next to each other to prove how fast his dialogue was. Filming was difficult for the cinematographers because the improvisation made it difficult to know what the characters were going to do. Rosalind Russell was also difficult to film because her lack of a sharp jawline required makeup artists to paint and blend a dark line under her jawline while shining a light on her face to simulate a more youthful appearance. Hawks encouraged aggressiveness and unexpectedness in the acting, a few times breaking the fourth wall in the film. At one point, Grant broke character because of something unscripted that Russell did and looked directly at the camera saying "Is she going to do that?" Hawks decided to leave this scene in the film, although it doesn't appear in the final cut. Owing to the numerous ensemble scenes, many retakes were necessary. Having learned from Bringing Up Baby (1938), Hawks added some straight supporting characters in order to balance out the leading characters. Arthur Rosson worked for three days on second unit footage at Columbia Ranch. Filming was completed on November 21, seven days past schedule. Unusually for the time period, the film contains no music besides the music that leads to the final fade out of the film. Ad-libs by Grant Grant's character describes Bellamy's character by saying "He looks like that fellow in the movies, you know ... Ralph Bellamy!" According to Bellamy, the remark was ad-libbed by Grant. Columbia studio head Harry Cohn thought it was too cheeky and ordered it removed, but Hawks insisted that it stay. Grant makes several other "inside" remarks in the film. When his character is arrested for kidnapping, he describes the horrendous fate suffered by the last person who crossed him: Archie Leach (Grant's birth name). Another line that people think is an inside remark is when Earl Williams attempts to get out of the rolltop desk he's been hiding in, Grant says, "Get back in there, you Mock Turtle." The line is a "cleaned-up" version of a line from the stage version of The Front Page ("Get back in there, you God damned turtle!") and Grant also played "The Mock Turtle"
