Question: What was the name of the English computer scientist who inspired a movie written by English screenwriter Craig Warner?

<P0-S0> Creatures is an artificial life (alife) computer program series, created in the mid-1990s by English computer scientist Steve Grand whilst working for the Cambridge video games developer Millennium Interactive. <P0-S1>  Gameplay focuses on raising alien creatures known as Norns, teaching them to survive, helping them explore their world, defending them against other species, and breeding them. <P0-S2>  Words can be taught to creatures by a learning computer (for verbs) or by repeating the name of the object while the creature is looking at it. <P0-S3>  After a creature understands language, the player can instruct their creature by typing in instructions, which the creature may choose to obey. <P0-S4>  A complete life cycle is modelled for the creatures - childhood, adolescence, adulthood, and senescence, each with their own particular needs. <P0-S5>  The gameplay is designed to foster an emotional bond between the player and their creatures. <P0-S6>  Rather than taking a scripted approach, Creatures series games were driven by detailed biological and neurological simulation and their unexpected results. <P0-S7>  There were six major Creatures releases from Creature Labs. <P0-S8>  Between 1996 and 2001, there were three principal games released, the Docking Station add-on (generally referenced as a separate game) and two children's games, and there were three games created for console systems. <P0-S9>  A sequel named "Creatures Online" was in development, with the artificial life technology from Creatures 3 and Docking Station updated to a 3D environment. <SEP> <P1-S0>  Warner wrote the screenplay for "Codebreaker", a film about Alan Turing. <P1-S1> Craig Warner (born 25 April 1964) is a multiple award-winning playwright and screenwriter who lives and works in Suffolk, England. <P1-S2>  He wrote "The Queen's Sister" for Channel 4, which was nominated for several BAFTA awards (including Best Single Drama), "Maxwell" for BBC2, which garnered a Broadcasting Press Guild Award nomination for Best Single Drama and won David Suchet an International Emmy for Best Actor, and "The Last Days of Lehman Brothers", for which Warner was longlisted for a BAFTA Craft Award for Best Writer, and which won him the award for Best Writer at the Seoul International Drama Awards in 2010. <P1-S3>  He wrote the mini-series "Julius Caesar" for Warner Bros., which gained Warner a Writers Guild Award nomination for Best Original Long-Form Drama, and he performed an extensive uncredited rewrite on "The Mists of Avalon", also for Warner Bros., which was nominated for a Writers Guild Award and nine Emmys, including Best Mini-series. <SEP> <P2-S0> Alan Mathison Turing ( ; 23 June 1912 – 7 June 1954) was an English computer scientist, mathematician, logician, cryptanalyst, philosopher and theoretical biologist. <SEP> <P3-S0> John G.F. Francis (born 1934) is an English computer scientist, who in 1961 published the QR algorithm for computing the eigenvalues and eigenvectors of matrices, which has been named as one of the ten most important algorithms of the twentieth century. <P3-S1>  The algorithm was also proposed independently by Vera N. Kublanovskaya of the Soviet Union in the same year.
