The movie is not, as you might assume from its title, a documentary about the day Connelly filmed that one love scene in The Hot Spot; rather, it’s a remake of the 1951 sci-fi classic, and Connelly joins a cast that already includes Keanu Reeves. From the article:
Story kicks off as aliens land on Earth carrying a message for all humans: Live in peace or be destroyed. Connelly is set to portray Helen Benson, the role Patricia Neal played in the 1951 original.
Earth is scheduled to begin filming in Vancouver next month, which gives Connelly time to wrap up work on He’s Just Not That Into You. According to Variety‘s report, Kathy Bates is also in talks to join The Day the Earth Stood Still.
