department heads, and, sometimes, the cast, may gather to watch that day or yesterday's footage, called dailies, and review their work. With workdays often lasting fourteen or eighteen hours in remote locations, film production tends to create a team spirit. When the entire film is "in the can", or in the completion of the production phase, it is customary for the production office to arrange a wrap party, to thank all the cast and crew for their efforts. For the production phase on live-action films, synchronizing work schedules of key cast and crew members is very important, since for many scenes, several cast members and most of the crew must be physically present at the same place at the same time (and bankable stars may need to rush from one project to another). Animated films have different workflow at the production phase, in that voice actors can record their takes in the recording studio at different times and may not see one another until the film's premiere. Animated films also have different crew, since most physical live-action tasks are either unnecessary or are simulated by various types of animators. Post-production This stage is usually thought of as starting when principal photography ends, but they may overlap. The bulk of post-production consists of the film editor reviewing the footage with the director and assembling the film out of selected takes. The production sound (dialogue) is also edited; music tracks and songs are composed and recorded if a film is intended to have a score; sound effects are designed and recorded. Any computer-generated visual effects are digitally added by an artist. Finally, all sound elements are mixed down into "stems", which are synchronized to the images on the screen, and the film is fully completed ("locked"). Distribution Distribution is the last stage, where the film is released to cinemas or, occasionally, directly to consumer media (VHS, VCD, DVD, Blu-ray) or direct download from a digital media provider. The film is duplicated as required (either onto film or hard disk drives) and distributed to cinemas for exhibition (screening). Press kits, posters, and other advertising materials are published, and the film is advertised and promoted. A B-roll clip may be released to the press based on raw footage shot for a "making of" documentary, which may include making-of clips as well as on-set interviews separate from those of the production company or distributor.
