Andy Muschietti was born on August 26. 1973 In 2013, Muschietti directed his debut film, the supernatural horror Mama, which he co-wrote with Neil Cross and his sister Barbara Muschietti, with the latter also acting as producer. It was based on Muschietti's three-minute short film Mamá, which attracted Guillermo del Toro, who stated that it had the "scariest" scenes he had "ever seen." The short convinced del Toro to executive produce the feature-length film, which starred Jessica Chastain, Nikolaj Coster-Waldau, Megan Charpentier and Isabelle Nelisse, and was released by Universal Pictures on January 18, 2013. The film grossed more than $146 million and had a budget of $15 million.
In September 2013, Universal hired Muschietti for a reboot of The Mummy franchise, but he left the project in May 2014 due to creative differences with Jon Spaihts' draft of the script. In July 2015, after the departure of Cary Fukunaga, Muschietti was hired by New Line Cinema to direct It, an adaptation of the Stephen King novel. Barbara produced along with Dan Lin, Roy Lee, Seth Grahame-Smith and David Katzenberg. The film will be in two parts.
