Harrison Ford on Gunsmoke

Just an odd bit to share – and if anyone has insight on why I’d like to hear it:

Caught an episode of Gunsmoke this weekend called Whelan’s Men. As soon as I saw Harrison Ford, I recognized him. He was prominent in the first 3 acts, but in the 4th – poof, gone, no explanation.

Perhaps the funniest part was when he shot a man across a barroom table without giving him a chance to draw. (Lucas, are you watching?!)

Anyway – I noticed he also did another Gunsmoke and a Kung Fu episode among other things – probably just enough work to keep going, but not enough to make a living.

Anyway – anybody know what happened to Ford in the last act of that Gunsmoke episode?
