10 Actors Who Made Sure They Weren't Seen In Star Wars
5. Bill Hader & Ben Schwartz - The Force Awakens
Comedian-actors Bill Hader and Ben Schwartz received rather unorthodox credits on The Force Awakens, not for voicing alien creatures but acting as "vocal consultants" for droid BB-8.
The pair were called in by J.J. Abrams to provide vocalisations for BB-8, which were then digitally manipulated to sound more droid-like and less, well, human, literally guaranteeing the pair couldn't be recognised.
Hader recently downplayed his work on the film, though, calling Abrams "sweet" for giving him a credit even though none of his original voiceover work was used in the film, but only his vocalisations into a digital talk-box.
Hader also noted that neither he nor Schwartz were credited for either of the sequels because, once BB-8's vocal template was set, anybody could provide sufficient vocalisations.
In the very least, their contributions are disguised enough that the pair could conceivably appear in future Star Wars media using voices that are more recognisably theirs.
