Fielding confirmed the IT Crowd star's involvement in two tweets about his show, which will air in 2012.
"Noel Fielding's Luxury Comedy, it's out in January on E4. The most fantastical, psychedelic show ever made. Like an aurora borealis sandwich," he wrote.
"First week of filming done! Highlights include Figo the fruit fly, Doorag's automatic poetry and Richard Ayoade as a hammerhead shark."
The show, which is expected to be a mix of sketches, characters, art and animation, was originally titled Noel Fielding: Boopus.
Speaking about the programme last year, Fielding said: "I want to make something in the spirit of Spike Milligan or The Kenny Everett Show but using modern techniques."
