The house-based tasks have already been filmed, with studio segments scheduled to be recorded between 3rd and 6th July at Pinewood Studios.
The channel says: "Seals will be broken, tasks will be read and unpredictable actions will then occur as the five comedians grapple with problems involving cuddles, candles and coconuts. Could you paint a rainbow in total darkness? Create a watercooler moment using a watercooler? Make Marmite? Yes? No? These fearless competitors both can and can't too."
Although it has yet to be confirmed, it is expected that the comedy will also return for a sixth series in 2018. Taskmaster has proved to be a big hit for UKTV, and producers Avalon have also sold the format to various TV channels abroad. Comedy Central USA is the latest to start working on its own version (news).
Speaking in an interview ahead of the recent series, creator Alex Horne talked about how long the show could go on for. He said: "I'd very happily do at least another five series; I think there are limitless tasks and there are so many people I want to be on it. I don't get bored in the slightest."
The following video has been released, which gives a glimpse of the new contestants in the task house:
