That series is now being shown on MeTV every Sunday night in sequential order and, as far a I can tell, uncut. Robert Duvall is just one of many top-rank actors who appeared over the lifetime of that show.
I've only started watching it recently and hadn't seen it since the 1960s so, in spite of its age, it's new and fresh (again) to me. I had forgotten just how tightly-written and well-acted The Fugitive was. Each hour long episode reveals a depth of character development and literacy lacking into a lot of today's fare. The booming voice of William Conrad intoning the setup at the start of each program ("a Quinn Martin production") is a signal that some quality television is ahead. It's not surprising that a skilled actor such as Robert Duvall appeared on that show.
I never knew that. Thanks for the info!!!!
