Mark Hamill has joked Carrie Fisher and Harrison Ford could've been "doing it in front of him" and he still wouldn't have caught on to their secret affair.
The three stars became household names thanks to their pivotal roles in the original Star Wars trilogy. It was recently revealed that Carrie, 60, had an off-set romance with on-screen love interest Harrison, divulging details in her new book, The Princess Diarist, named after her alter ego Princess Leia.
Despite being around the pair all the time during filming, Mark, who plays Luke Skywalker, admits he was blissfully unaware of his co-stars’ shenanigans.
"I was so self-involved at that point, they could've been doing it in front of me and I wouldn't have noticed," the 65-year-old laughed to Entertainment Tonight. "I was single and had my own agenda."
He thinks it’s lucky he didn’t know what was going on between the pair though, as he feels it may have “distracted” their short-lived romance.
On the topic of workplace romances in the showbiz industry Mark describes them as “commonplace”, however has learnt from own experiences that it can end up being a sticky situation if things go wrong. Mark dated his General Hospital co-star Anne Wyndham in the early 70s, after the pair starred as siblings in the TV show.
"If the relationship doesn't last and you're on a TV series and you got four more seasons to go, it can be really awkward," he noted.
If Carrie’s book is anything to go by, Mark was extremely close to walking in on Carrie and Harrison during their alone time, as the actress revealed one of the few times the couple had a “sleepover” at the Indiana Jones star's apartment it was interrupted by the actor.
“Mark... dropped by unannounced," she wrote in her book, noting the time was 11am. "Clearly I hadn't just dropped by for brunch."
To ease the awkwardness, Carrie remembers Harrison jokingly took her hand and “solemnly declared” they were engaged.
The three stars also appeared in the latest Star Wars flick, The Force Awakens, with Carrie and Mark appearing in the upcoming eighth instalment as well.
