Filmmaker Brett Ratner, known for the Rush Hour series, joined former US President Donald Trump on a diplomatic trip to China, where he plans to scout locations for the much-anticipated Rush Hour 4. This visit, which includes meetings with Chinese film distribution partners and potential crew members, aims to set the stage for filming significant portions of the movie in China. The original Rush Hour, released in 1998, became a global hit, followed by successful sequels in 2001 and 2007. Despite facing career setbacks due to sexual misconduct allegations in 2017, Ratner remains focused on bringing Rush Hour 4 to fruition. He has expressed that this project is his primary goal, stating that directing a recent documentary was not intended as a comeback but rather a separate endeavor.
