Studio logos and titles are usually one of the first things shown in films. Larger studios like Warner Bros. have consistent logos while smaller studios may just use titles. The logo or style it is presented in can suggest the genre, like a dark Warner Bros. logo hinting at a thriller. Films then establish the genre through titles, actors, shots, editing and other elements to set the tone and mood for viewers. Main characters are often introduced in the first few minutes through mid and close shots to portray their role and fit with the implied genre. Sound is also key to conveying genre, like jazz music in Gran Torino signaling a somber film.
