Do toy retailers collaborate on cross promotions with film studios?

The single source supplied focuses exclusively on the 2023 live‑action Barbie film directed by Greta Gerwig and does not mention any marketing or promotional activities involving toy retailers and film studios. No references to co‑promotions, joint marketing campaigns, or retail partnerships are present in the text. Without additional data, we cannot confirm or deny that such collaborations occur. Consequently, based on the verified evidence, we have no basis to assert that toy retailers participate in cross promotions with film studios. Further research would be needed to identify any real-world examples of this practice.
