A storyline from the Poldark novels which sees Ross rape his ex will be absent from the new series of the hit drama.
Instead, Ross Poldark, played by Aidan Turner, will have a romance with first love Elizabeth, played by Heida Reed, in the second instalment when it returns next month.
The Sun quoted Aidan as saying: "It seems consensual, and it just seems right. He goes to talk. He doesn't go to commit a crime.
"They talk and it seems like there is still this spark between them, this unfinished business emotionally. He doesn't force himself upon her."
A spokesman from Mammoth Screen said: "Winston Graham's version of events is open to interpretation. Ours is not. Many fans haven't read the books and don't appreciate spoilers, so we invite all viewers to watch the episode when it comes out and then make up their own mind?."
Six million viewers tuned in to the emotional final episode of Poldark's first series last year.
The finale featured the sudden death of Ross and Demelza's (Eleanor Tomlinson) baby daughter Julia and ended with a cliffhanger which will run into the second series.
Meanwhile Eleanor told Vogue magazine that she and her co-star disagree constantly.
"He's beautiful to look at, so it's hard not to fancy him, but fortunately we don't feel like that about each other!" the actress said.
"We're great friends but we disagree all the time. We've both got a temper, we're both strong people - there are definitely similarities between us and our characters."
The BBC is already planning a third series of the drama, set in Cornwall.
Based on the novels of Winston Graham, the drama was originally made for TV in the 1970s when it attracted audiences of 15 million.
The remake helped BBC One to its highest share of an audience in a decade.
