Two actors have been cast for the pilot of the new spin-off series of AMC’s The Walking Dead.

The two actors hired were revealed as Frank Dillane and Alycia Debnam Carey, according to Deadline. They will play the children of the lead female character on the show, which is said to take place in the same apocalyptic world of the main series but in a different place. That character will also be leading with a male character who was a teacher and divorcee.

The only detail regarding the main female character is that she used to be a guidance counselor, Entertainment Weekly reported. Dillane plays her son who had a drug problem in his past, while Debnam Carey’s is her daughter, with “ambitious” being the only detail given of that character. The main female character hasn’t reportedly been cast yet, nor has the character’s name been revealed.

EW also reported details about the cast actors. Dillane was seen as Tom Riddle in Harry Potter and the Half-Blood Prince, while Debnam Carey was in Into the Storm. Dave Erikson and Robert Kirkman co-created the new series.
