Callum Scott Howells and Gabrielle Creevy to lead Channel 4's The Night They Vanished

Deadline reported Callum Scott Howells will play Cai and Gabrielle Creevy will play Anna in The Night They Vanished. The six-part thriller adapts Vanessa Savage's novel and is filming in Wales. Channel 4 pre-bought the series, meaning it agreed to air it before filming finished. BBC Studios' CliffEdge Entertainment is producing and selling it worldwide, according to Deadline.
