Her character was supposed to be 13."I was super teenage [with] puberty insanity happening," Arngrim explained. "Shes just barely 13. This cat is, hes playing I guess 16, 17. Hes in his late 20s."Bob Marsic, who played Simms, was 22."Its young girls children accosting a grown manwho they havenot been introduced to," said Arngrim about how the characters reacted to Simms appearance."That would not happen today, right?" Bob asked. "That casting a full-grown adult to play or even kiss and it was an innocent kiss, but it's a kiss a minor."Filming was awkward from the start, Arngrim recalled, noting that she hadnt met her on-screen love interest before they started filming.CLICK HERE TO SIGN UP FOR THE ENTERTAINMENT NEWSLETTER"I think we were like kissing on the first day or something," she said. "Maybe the second day two? It was pretty quick, it was like, 'Hi, introduce yourself, now you're in love.'"Arngrim noted that if a similar scene were filmed today, there wouldnt be a significant age gap between the young actors. An intimacy coordinator, which didnt exist at the time, would also be on set.The former child star described how at one point, Marsic brought his girlfriend to the set while the episode was filmed."That was another of the weird moments," said Arngrim on the podcast. "His girlfriend shows up, and it was weird because it was like there was this vague thing of her wanting to be there for the romantic scenes.""I was like, does this woman think that I am a threat?" she chuckled. "Really? This 15-year-old pimply girl? No. No. I am not a threat to your relationship. I am not stealing your man."Back in June 2024, Butler spoke to Fox News Digital about how he had struggled with anxiety after discovering that he would be giving his co-star, 15-year-old Melissa Gilbert, her first kiss both on-screen and in real life.WATCH: LITTLE HOUSE ON THE PRAIRIE CHILD STAR SAYS SET WAS LIKE MAD MENButler was 23 when he was cast in the popular TV show, which aired from 1974 to 1983."You just couldnt do it today," the actor, who played Almanzo Wilder in "Little House," told Fox News Digital. "There would be way too much blowback. Its remarkable that we didnt get more blowback than we did. . . . But I think it was handled so tastefully that people forgot about the age difference.""I think the audience had been watching Melissa for years and loved her incredibly," Butler shared. "They wanted to see when she, so honestly and innocently, declared her love for this young man. She fell in love from the first time she laid eyes on him. The audience was prepared to go right along with that."According to Butler, the characters from the original book series were supposed to have a 10-year age difference. He noted that Gilbert had "complete trust" in her TV dad, who carefully supervised the scene."That was a very powerful relationship Melissa had in her life, the one she had with Michael Landon," said Butler. "When Michael said, This is the guy for you, she was prepared to suspend all of her anxieties and just step into it. And Michael never led anyone wrong in the series. He really had it down. He knew what he was doing. He believed very strongly in his creative instincts. He trusted that it would work.""Im just really grateful that I was the guy that he felt he could trust with this," Butler added.LIKE WHAT YOURE READING?

"Melissa had no experience. Shed never been on a date. Never kissed anyone. Never did anything like that. That was still all ahead of her. So to ask her to step into that when she had no real life experience? It does speak to Melissas gumption and her courage. She just did it. She put all of her anxieties aside and just stepped in. She knew what she had to do to be the Laura that she was supposed to be."The pair smoochedin the episode titled "Sweet Sixteen." Butler said that nearly 100 people surrounded them on set to make sure the shot was perfect."My job was to make it as easy for her as possible by really being the gentleman I was raised to be," Butler shared. "Theres been no casting pairing like what they did with us since then. That casting could simply never happen today. Certainly not on a mainstream television show."
