The classic sci-fi series was celebrated at San Diego’s Comic-Con July 18 for the X-Files‘ 20th anniversary where the stars, writers and producers paneled to address a possible third X-Files movie, Breaking Bad‘s tie into the series and Dana Scully and Fox Mulder’s relationship.

Moderator Michael Schneider of TV Guide first stirred the panel with asking David Duchovny and Gillian Anderson if they had a different perspective now on anything relating to the show. The caught-off-guard actors paused before Anderson responded sensually, Rolling Stone reported.

“I guess I didn’t realize that Mulder was so cool until a few years later,” she said. “And I thought, ‘Damn, shoulda got there sooner.'” Scully and Mulder eventually did mess around later in the series. Fans longed for more direct information on Mulder and Scully’s sexual escapades. “Well, something happened. Because we have a child,” Anderson said. She recalled a sex scene between them was shot at one point, but never aired. “It’s somewhere,” the actress added, reported the Huffington Post.

X-Files writer Vince Gilligan noted that there would be no Breaking Bad without his seven years of experience writing for the popular sci-fi series. “It was like going to film school, except getting paid to attend, and I was lucky as hell I was a part of it,” Gilligan said. Gilligan met Breaking Bad star Bryan Cranston during a season six episode of X-Files, who left a lasting impression in Gilligan to later consider him for the role of Walter White.

The most pressing issue was whether there would be a third X-Files movie which no direct answer was given. “You need a reason to get excited about going on and doing it again, because it’s hard, hard work, but this is very inspirational,” series creator Chris Carter said of the possibility of a third movie.
