As promised, here's an excerpt from the 1960 article re: Jack Kelly and Roger Moore on Maverick. It was written by Cecil Smith and it's mostly in the form of a candid conversation in which old hand JK tries to teach newbie Moore (who was just joining the series as "Cousin Beau") what it means to be a Maverick:
"JK: 'To begin with, Beau is rather the white sheep of the Mavericks. He was born in Texas, but [lived] in England. He was a hero in the Civil War and there's nothing a Maverick abhors like heroism or bravery.'RM: 'I rather think if Maverick turned up today, he'd be rather like Francis Powers.'
JK: 'No, Powers hasn't the guts Maverick has.'
RM: 'But, is it guts, really?'
JK: 'It's the manifestation of guts. It's ingenuity. It's sophistication. And it's intestinal fortitude...Beau, despite being a white sheep, was fortunate enough to have been born a Maverick. So, some of the real Maverick point of view rubs off.'
RM: 'Jack, see that girl at the end of the bar--isn't that lovely?'
JK: 'See what I mean? That's a Maverick remark. But a Maverick would go up and meet her, introduce himself. See Maverick is wishful thinking. Maverick does what every man wants to do--but because of conventions or timidity or public opinion won't'.
RM: 'I see Maverick as a sort of modern Robin Hood.'
JK: 'Not exactly. Maverick would be more inclined to steal from the poor and give to the rich.'
RM: 'I see--he's rather altruistic in reverse.'
JK: 'Exactly. He doesn't attack conventions. He ignores them. He symbolizes man's wishful thinking.'
RM: 'I'd hate to be like Maverick. My wife would kill me.'
JK: 'No she would not. There's a perverse side of a woman that loves a Maverick.' [B27: !!!!]
RM: '...I suppose there are parts of Maverick in me. In every man. That's what you draw on in interpreting the role.'
JK: 'Now, to meet that girl...'
[B27: Moore chats up the girl, but returns with a man!]
RM: 'Say, you know that lass at the bar, the attractive one. I'd like you to meet her husband.'
JK (holding his head): 'Oh no, he'll never make a Maverick!'"
