I peeked in at TCM in the middle of the day earlier in the week and One Million BC was on-- not One Million Years BC with Racquel Welch, but the original One Million BC with Victor Mature and Carole Landis. Great movie. I wish that one would come out on DVD.
I saw about twenty minutes of a print of it, but was thoroughly bored. It is notable for being the last film that D.W. Griffith was involved with, although he left the project before filming, so his involvement was limited.
