So far, two characters and a helicopter have crossed over from parent series The Walking Dead to spin-off Fear the Walking Dead, and with the universe of the franchise ever-expanding, with another show and a movie trilogy in the works, further crossovers and spin-offs can't be ruled out. We wouldn't say anything is possible — it seems unlikely that anyone would come back from the dead as anything other than a zombie — but possibilities feel more open than ever before, and it's fun to think about what could happen. That's why when TV Guide sat down with the cast of Fear the Walking Dead at the ATX Television Festival, we asked what Walking Dead characters they'd like their characters to meet in a movie or crossover, and what their dream spin-off would be.

"If there's anyone who would be in the movie with Rick [Andrew Lincoln], it would be Al [Maggie Grace]," Ruben Blades predicted, since Al is the Fear character who's had an encounter with the mysterious folks who took Rick. "I hope they sneak Salazar in there to go rescue Al."

"And I can just pop in there a little," added Alexa Nisenson, who plays young survivor Charlie.

"Absolutely," Blades said. "We'll both go together because we make a good team."

If there's another Rick-Morgan reunion in the works, Lennie James is up for it. "I had a great time working with Andy," James said. "I'd work with him any day of the week. So any opportunity to be back in front of the camera, hanging out on set with him, I would absolutely jump at."

As for Walking Dead characters they'd like theirs to meet, Maggie Grace said Carol (Melissa McBride). She thinks Al and Carol would see eye to eye, having gone through similar isolated journeys. Nisenson said Judith Grimes (Cailey Fleming) because they could be li'l ass-kickers together. And Blades said Daryl (Norman Reedus) or Negan (Jeffrey Dean Morgan) — Daryl because they're both loners who would relate to each other and Negan because he used to be a very ruthless man who's changing into someone kinder, just like Salazar.

And according to Karen David, a Morgan spin-off movie would have to be called The Return of Momo, because he's Momo.

Fear the Walking Dead airs Sundays at 9/8c on AMC. Previous seasons are available to stream on Hulu.
