The Life's Too Short actor is set to star as Derek Noakes in the one-off comedy-drama on Channel 4 tomorrow night (April 12).
He announced to his Twitter followers that while Derek is currently a one-off production, a full series will likely be on the way eventually.
"Thanks again you lovely twonks for all the good wishes for Derek tomorrow night. It's only a one-off, but I am slowly writing a series," he explained.
The comedian recently defended the show against those who believe it makes fun of disabled people.
Derek also stars Karl Pilkington in his first acting role. Gervais recently said that his part is very similar to the man himself.
The comedy will air on Channel 4 on Thursday, April 12 at 10pm.
