And then in 2014, the reboot wascanceled, which Duffy blamed onTNT’s regime change.

He admitted Hagman’s death probably played a part as well, considering ratings dropped afterward.

That tradition continued on theDallasreboot, where Duffy directed an episode in 2014.

Will there be a Step by Step reboot?

His tune seems to have changed slightly since then, taking on a less optimistic tone.

The whys generally are ‘Because there’s a ready made audience and because it’ll be successful.

That’s not the why.

The why has to be inherent in the writing and the premise of the show.

And I can’t think of a why.

I don’t forsee it happening."

Sorry, Lambert-Foster family fans.

TheMan from Atlantisbook was released in 2016, marking Duffy’s debut as a novel writer.

The book provides the backstory that the show never did for Duffy’s character, Mark Harris.

These were his words and his story.

The plan was for Duffy to write a trilogy, but he has yet to release a follow up.

“But I’m happy.

It made me satisfied.

It completed my idea of what the character of Mark Harris was supposed to be initially.”

Thus, the bad blood.

Duffy told Lakin’sWorst Ever Podcastthat there are someStep by Steppeople he doesn’t want to work with again.

He didn’t name names, instead saying “You know who you are.”

“We will be together eternally.”

There’s something different about him…

And we’re not just saying that because he’s gone grey and grew facial hair.

It’s such a drastic change that his ‘do madeheadlineswhen he appeared on a German TV show in 2018.

Nobody wants to see that, so the ponytail look is probably a good call.

We’ll eventually get used to it.

Obviously, maintaining a ranch is a lot of work, so Duffy has a ranch manager helping him.

But he likes to get his hands dirty and contribute where he can, including thecarpentrytasks.

You don’t see a whole lot of that in LA.

The tributes don’t end there.

Together they amassed an impressive art collection one that he saidDallaspaid for during their 40-plus years together.

But following Rosser’s death in 2017, Duffy decided it was time to sell much of the collection.

It wasn’t easy.

He told theHollywood Reporter"It breaks my heart to not have it available on a daily basis."

And after we’re gone, somebody else will experience it.

I’m joyful that it’s going to have a new home."
