It seems while Millennium rests, The X-Files continues. After a return last year with season 10, TV-Wise broke the news in October 2016 that season 11 is likely on the cards, and with that, rumours of a more traditional season structure (season 10 was six episodes). Letest rumours indicate a middleground with a possible 10 episode structure.
I would suspect Frank Black would be an unlikely suspect to resurface for the season (pessimistic me), but more X-Files is bound to sit well with many Millennium fans.
Watch this space, or perhaps more smartly, watch TV-Wise for The X-Files news – the news site was responsible for the breaking news on season 10 as well.
