The word "re-casts" is defined as the action of recasting something, or changing its mold, form or shape. Antonyms for "re-casts" would include words such as "maintains," "preserves," "upholds" or "keeps unchanged." These opposing terms suggest a continuity of form or structure, rather than a re-imagining or re-shaping of something. For example, if a movie director decided to maintain the same cast for a sequel, it would be an antonym for "re-casts," as the actors would not need to be changed or adjusted. Similarly, if a company upholds its traditional business practices and does not introduce any new changes or alterations, it would also be an antonym for "re-casts.
