Warner Bros. sought a stake in Nolan's production of Interstellar from Paramount, despite their traditional rivalry, and agreed to give Paramount its rights to co-finance the next film in the Friday the 13th horror franchise, with a stake in a future film based on the television series South Park. Warner Bros. also agreed to let Paramount co-finance an indeterminate "A-list" property. In August 2013, Legendary Pictures finalized an agreement with Warner Bros. to finance approximately 25% of the film's production. Although it failed to renew its eight-year production partnership with Warner Bros., Legendary reportedly agreed to forgo financing Batman v Superman: Dawn of Justice (2016) in exchange for the stake in Interstellar.
