Una vida marcada

I remember seeing this movie many times on "Picture For A Sunday Afternoon", "The Early Show" and "The Million Dollar Movie" and I always loved watching it. I thought Richard Conte played one of the best "bad guy" roles I'd ever seen. Using his girlfriend, kid brother and even his mother to facilitate his life of crime. Victor Mature gives his usual solid performance and Fred Clark as his assistant was interesting as well considering that his future seemed to be bumbling comedic bit player. The sleazy lawyer and murderous masseuse were also well cast. What I can't understand is why this flick as well as One Million BC aren't available on DVD.
