"I fell into acting and it was something I did for seven years, 77-year-old Roger Green said.
"I was swanning around doing nothing, as you do when you're a sheep farmer in London on an OE, and there was plenty of drinking, plenty of partying and plenty of women," 77-year-old Roger Green said.
"I used to get up to all sorts of pranks, some people said I actually was James Bond."
Green was told by director Guy Hamilton he had a great chance of landing the role.
"At that point I thought, 'give me another brandy', because anyone who plays Bond becomes a world star."
He missed his chance at global fame when Connery signed on to continue in the role.
Agreeing he and his grandson have a lot in common, Roger, who was a Junior All Black in 1958, says he's tremendously proud of Arthur - and many are picking up the likeness.
"A good friend who I went to school with rang me the other day after watching Art on the show and said he thought he was watching me," he said.
"I'm proud of him, he's a bit like me. I fell into this thing in London after a friend of mine who became my agent said, 'I think you'd make a good Bond.' I just went along with the flow. Art kind of got involved in this the same way.
"I suppose the whole entertainment thing comes quite naturally to us.
"We're showmen and I think it's great. I believe Art has handled it brilliantly."
Arthur says he and his grandfather share a confident approach to life and being in the spotlight is something they have both embraced.
But the reality TV star, whose show has seen 21 Kiwi women vying to win his heart, says he is looking forward to this week's finale so that he can shed his "secret life" and be seen in public with a woman on his arm.
"No more secrets.
"It's going to be great to have a normal relationship because at the moment it's like having a secret life with the girl that I've chosen."
Both Greens will tune in for the big finale, though the star of the show says it will be uncomfortable viewing.
"I'm not necessarily looking forward to watching the last couple of episodes because for me, it was quite emotional.
"It was quite full-on and I'll be reliving that," he said.
"The hardest part of the whole experience has definitely been having to send people home." NZME.
