I'll have to check this one out again (it's been YEARS), but I loathe Jason Robards...
Im not a big fan of his either but--with him in movies like: The Journey--made me change my mind on him a bit. He was good--VERY good in that movie ;-))
Shame that instead of the two who took Deforrest Kelleys and the other actors places in the movie--shame they couldnt have been both: Charles Bronson and James Coburn or even Steve McQueen.
