24 writer and executive producer David Fury has responded to a fan question and said that the Counter Terrorist Unit is unlikely to return for 24: Live Another Day. CTU has been a staple of the series, appearing in seven of the eight seasons, but it looks like the writers are serious about taking the series in a different direction.
“@JUrciuoli19: where is 24 LAD taking place next season and will CTU be back?” Too soon to announce where; CTU's return unlikely.
