Freddie Stroma, his Time After Time
co-star Genesis Rodriguez, and the show's executive producer Marcos Siega, sat down with ET's Leanne Aguilera at Comic-Con on Saturday, where the 29-year-old actor -- who's engaged to his UnREAL co-star
, Johanna Braddy -- admitted that wedding planning has been "good" but "stressful."
"[We're] getting there," he said. "It's going well."
The British actor also revealed that his fiancée isn't the only one doing the work for their upcoming nuptials. "I'm getting involved," he said. "How do you even know you're halfway through it? I think we're about halfway through."
Stroma and Braddy, 28, met on the first season of Lifetime's faux reality drama and got engaged in May after one year of dating.
As for Stroma's upcoming show, Time After Time, Siega described the drama -- which is based on Karl Alexander's sci-fi novel, Time After Time -- to ET as "a big fun action-adventure love story" about a fictionalized version of H.G. Wells who has built a time machine. Wells discovers that his best friend, John Stevenson, is actually Jack the Ripper, and after Stevenson flees in the time machine, he pursues his pal into the present.
"It's sort of classic Kevin Williamson," Siega said of his fellow executive producer on Time After Time. "When you think of The Vampire Diaries or The Following, there was a love triangle, and we have the same inherent premise."
"The premise of the show is really the adventures of H.G. Wells in present day, and then some time traveling is what inspired all of the writings of his novels, like The Time Machine, The Invisible Man, and War of the Worlds," he continued. "So season one is The Island of Dr. Moreau, and our story is what sort of inspired his novel."
"There's a lot of fun moments," Stroma added.
As if love triangles and time travel weren't enough, the show also features Josh Bowman, who Stroma noted "is an attractive young man" and Siega said "looks fantastic without a shirt on."
Stroma isn't the only actor who talked wedding bells at Comic-Con
co-stars David Giuntoli and Bitsie Tulloch revealed to ET that they were engaged during their interview at the Hard Rock Hotel. Check out Tulloch's gorgeous ring
