By adopting the molding method and the film hot press forming mold, wrinkling in the corner of the film insert can be effectively avoided, thus enhancing the quality of the film insert.

In the film, the speech therapist used a similar method by having King George insert an "ah" sound into a sentence before a treacherous word.

Later in the film while Andy carves his name into his cell wall (seen twice in the film), Darabont's hands are used as well in the insert shot.
