Guest: Open Lines with Dr. David Livingston. The first segment of this Open Lines program was not space related as I summarized my experiences on my son's movie set in the Santa Barbara, CA area two weeks ago using a tiger in the movie. During this segment, I discussed what it was like working with a wild animal, how the actors and those on the set were trained to behave with the tiger, what the trainers do, how shots are filmed, and what it's like to work, play, and handle a tiger.
