Cass began his career in the motion picture industry as an extra - but
soon he was alternating between acting parts and stunt work. The stunt
work eventually prevailed and Cass went on to become one of Hollywood's
top stunt co-ordinators and Second Unit Directors. This led to his
producing several films which, in turn, led to first-unit directing.
Dave has co-produced Miramax Films' Texas Rangers (2001); a trio of Burt Reynolds' TV
movies titled Logan: Ein Bulle unter Verdacht (1998), for the TNT network - writing one episode, and
directing another, Logan: Das zweite Gesicht (1999). He has also co-written several other films
including Priester der Dunkelheit (1972) and Hard Ground (2003). Dave was the director of The Hallmark
Channel's mini-series, Johnson County War (2002), another take on the infamous Wyoming
cattle wars, this one an adaptation by Larry McMurtry. Cass has directed two
Gentle Ben TV movies, plus Night of the Wolf (2002), starring Anne Archer and Robert Urich, for
Animal Planet.
And from Hallmark, again, David directed a city girl/country boy love
story, Straight from the Heart (2003), which garnered the highest ratings ever for a Hallmark
Channel TV Movie.
