A mix of North American and British talent will topline an untitled BBC/Science Channel movie about the search for what caused the 1986 Challenger Space Shuttle explosion. William Hurt and Bruce Greenwood will star as physicist Richard Feynman and Air Force General Donald Kutyna, respectively. Feynman, a Nobel Prize winner who also assisted on the Manhattan Project, was instrumental in uncovering the truth, as was Kutyna whom he befriended in the process. Brian Dennehy is also on board as William Rogers, the chair of the presidential commission and Joanne Whalley will play Feynman’s wife. British actors Kevin McNally (Downton Abbey), Henry Goodman (The Damned United) and Eve Best (Nurse Jackie) also star. Shooting starts this month on the TV movie that James Hawes is directing from a script by Kate Gartside. Great Expectations’ Laurie Borg is producing. Exec producers are Mark Hedgecoe, Cassian Harrison and Rocky Collins.
