Trading Places [SEP] Release
The summer of 1983 (June–September) was predicted to surpass the previous year's record-breaking $1.4billion in theater tickets sold. The season featured expected hits such as the third installment in the "Star Wars" series, "Return of the Jedi", "Superman III", and the latest James Bond film "Octopussy". Over 40 films were scheduled for release over the 16-week period. Studios had to strategize their releases to avoid damaging their own films' performances by pitting them against better-performing competition. Paramount Studios opted to position "Trading Places" release at the start of summer, as those films expected to do well would benefit from being in theaters longer during this busy period.
