According to a report in the Daily Mirror, an insider working at the show's production company Talkback Thames says comedy writer and actor Morris is set to play the boss of the plush company where the main characters work in a dingy basement.
The paper adds that Morris, who is famously reclusive, was hoping to keep his role a secret.
This will be his first appearance on TV since his show 'Jam' on Channel 4. However, he wrote and directed another sitcom on the channel this year, 'Nathan Barley', which received mixed reviews.
His spoof documentary series 'Brass Eye', which infamously fooled a number of celebrities and politicians into thinking it was genuine, courted controversy and viewer complaints in particular for a show about paedophilia and the media.
'The IT Crowd' is written by 'Father Ted' and 'Black Books' writer Graham Linehan and is part of Channel 4's new season for winter 2006. It will be screened from next February on Friday nights and will form part of a revival of Channel 4's successful comedy night concept.
Also being screened on Friday nights will be hit US sitcom 'My Name is Earl', starring Jason Lee, and the return of '8 out of 10 Cats' and 'The Friday Night Project'.
