Actor Blair Underwood's Ironside remake has been axed by TV bosses after just three episodes. The police drama, based on the classic series which ran in the 1960s and 1970s, starred Underwood as a paraplegic detective in the title role made famous by Raymond Burr. It debuted in the U.S. at the start of October (13), but has since been dropped from the programme line-up at the NBC network due to low ratings. Its fourth and final episode will air on Wednesday (23Oct13). Ironside isn't the only show NBC executives have cancelled - Welcome to the Family, a comedy starring Glee's Mike O'Malley, has also been nixed.
