Daniel Sharman thinks that a crossover between AMC’s “The Walking Dead” and “Fear the Walking Dead” would be a bad idea.

In a recent interview with SciFiNow, Sharman — who plays Troy Otto on “Fear the Walking Dead” — explained why he thinks it would be better for both shows to remain separate from one another. “I think what’s amazing about this world that’s been created over both shows is that the scale of it is so massive,” Sharman said. “And I think personally not only do you have to deal with the time jump, you also have to deal with the fact that if they do cross over in some way then the world becomes smaller.”

But if the shows end up doing a crossover in the future, Sharman said that it would have to be “coincidental and very brief.”

“That might be an interesting thing,” said the British actor. “But the idea that the worlds will merge and they’ll end up living among each other, I don’t know. For me, I just think it would be too obvious. A bit gimmicky.”

Sharman’s comments came a month after Robert Kirkman — creator of both shows — said at San Diego Comic-Con that merging the shows for a crossover event would be something they’d like to do if they could figure it out. “I think that it's something that we would love to try and work out, and we know the fans would love it,” Kirkman said (via IGN). “It’s something that’s very complicated because of that time gap, so we'll just have to see.”

But unlike other networks and producers who would quickly jump at the opportunity to use a crossover event to increase ratings, executive producer Gale Anne Hurd previously revealed that AMC and her fellow producers are more wary in doing a crossover between the two shows.

“[Doing a crossover] is truly jumping the shark because it’s not an outgrowth of who your characters are and what it is that each wants and needs,” Hurd told Deadline in 2015. “You’re trying to contort them so that they’ll fit into a plot line that simply isn’t logical. I think the thing is to care for the characters.”

“That’s what has enabled ‘The Walking Dead’ to go into [several] season[s] incredibly strong, because you care about individual characters be it Rick (Andrew Lincoln), Michonne (Danai Gurira) or Daryl Dixon (Norman Reedus) or Morgan (Lennie James),” Hurd added. “You care about the new characters that are introduced. You know what the rules are and you also know that whatever you expect will happen likely won’t, or if it does it’ll happen with a unique twist. So I think the same will apply to ‘Fear.’”

“Fear the Walking Dead” Season 3B premieres on Sunday, Sept. 10, at 9 p.m. EDT on AMC, while “The Walking Dead” Season 8 premieres on Oct. 22 in the same time slot.
