Recording sessions did take place at Disney; the crew found and renovated a small derelict property in Hollywood. Rees's direction primarily consisted of ensuring the performances were as natural and realistic as possible. When recording, Rees first had each scene delivered as written, and then allowed the voice actors to play around with the dialogue, and ended up using many of the improvised lines in the final film. Unusual for the time, some of the recordings were done in group sessions.
