An actor who gradually segued into writing and directing, David Alford got his start on camera in the 1999 sci-fi comedy musical Existo before penning the script for the 2000 made-for-television drama On Music Row. In the following years, Alford appeared in such features as The Last Castle, Changing Hearts, and Charlie's War while penning the screenplays for Yard Sale, Adrenaline, and Prisoner -- as well as appearing in each of them. 2007's Prisoner -- a tense tale of an egotistical filmmaker held captive in a crumbling, remote penitentiary -- also marked Alford's directorial debut.
