ABSTRACT
Automated Dialogue Replacement is the dubbing in of replacement lines or additional lines for an actor. The process is automatic in that the actor can repeat a given line in synchronization with picture until they get the performance the way the director wants it to be. The best ADR or "looping" is the recordings you don't have to do, because you took the time to record good dialogue during production. Action movies tend to have more ADR as they have noisier sets. The war movie, Apocalypse, is said to have required more than 80 percent of the dialogue to be dubbed. In a drama it's more common to have only about 10 percent ADR since the sets are usually quieter. ADR lines can be added to an actor who has their back to the camera so lip synchronization isn't critical. This process is called "cheating a line." Sometimes this type of ADR is referred to as Additional Dialogue Recording.
