Since the late eighties Morgan Creek productions have dabbled with multiple genres whilst pursuing box office success. At times, they have been successful with such populist movies as Young Guns and Robin Hood: Prince of Thieves. However, for every film that proved financially viable there were often two more that failed to gain an audience. Yet, despite having the business acumen to commission the best writing and directing talent available, co-founders James G. Robinson and Joe Roth have often been at odds with such creative individuals, resulting in many troubled productions. Horror writer and director Clive Barker endured an arduous experience while making Nightbreed, which was based upon his own novella. It was such a negative experience, resulting in a movie that was far from his initial vision, that Barker effectively quit film making. A similar experience befell William Peter Blatty when he was given an opportunity to film a direct sequel to The Exorcist based upon his novel Legion.
