Classic TV fans alert: Janet Arness, widow of James Arness, was interviewed by Rob Word, along with Arness' colleague and friend, actor Bruce Boxleitner. It's an essential for lovers of Gunsmoke, vintage TV and film, and James Arness.

Just google: How I Met and Married Gunsmoke's James Arness .
It's long, about 28 minutes, but well worth the watch. There's a shorter version too, but it leaves out too much.
She discusses his relationship with his brother, Peter Graves, his meeting and courtship of her (in the last year of Gunsmoke), friendship with John Wayne, aspects of his personality like his conscientiousness and fanatical sense of privacy, and more. She's joined by his pal, impish Bruce Boxleitner, who adds more colorful anecdotes. Both allude to the fact that in real life, Arness was much more of a prankster with a goofy humor, than one would expect from serious "Marshall Matt Dillon".
He loved to laugh, and did it with gusto:

Janet Arness met him through her employer. She worked for a women's clothing store, and the proprietor was married to Arness's makeup man.
You'll be struck by how unassuming and adorable Janet Arness is. Completely down to earth, and not a plastic Hollywood wife, at all. Bruce Boxleitner is unexpectedly fun too.

Have always respected James Arness, World War II winner of the Bronze Star, the Purple Heart, and many other medals. His leg was splintered at the horrific battle at Anzio, and he suffered pain the rest of his life due to war injuries....
