The film industry has several types of cue sheets that help convey information to the editors and mixers who'll be working with the material.
The ADR supervisor prepares ADR cue sheets for the ADR recorders, sound editors, and the actors who'll be reading those lines. These cue sheets indicate which lines need to be redone, the start and end times of each line, and generally the reason for needing to do the line.
Sound editors prepare cue sheets so that the remix engineers are aware of what sound effects are on what tracks and the start and end points for each effect.
As film mixing is now done using digital audio workstations, like Pro Tools, sound effect cue sheets are less necessary, since the workstation timeline displays the same information.
However, some remix engineers still prefer to have cue sheets, since not all mixing stages have computer monitors for every mixer, and also because some engineers like to be able to write mixing notes on the cue sheets.
