Show creator Graham Linehan made the announcement during a Q&A session at Germany's re:publica conference.
According to the report, the finale special will be 40 minutes long and all cast members are on board. The script was penned sometime ago but due to the commitments of the show's stars, it was pushed back - until now! An official air-date has not yet been released.
The IT Crowd stars Chris O'Dowd, Richard Ayoade and Katherine Parkinson (plus the delightful Matt Berry!) as the haphazard IT team of the fictional Reynholm Industries.
