 In February 2001 , Ehren Kruger sold his spec script to Metro @-@ Goldwyn @-@ Mayer ( MGM ) . With Gilliam 's hiring as director , the script was rewritten by Gilliam and Tony Grisoni , but the Writers Guild of America refused to credit them for their work , thus Kruger received sole credit . MGM eventually dropped out as distributor , but decided to co @-@ finance The Brothers Grimm with Dimension Films and Summit Entertainment , while Dimension took over distribution duties .
