Less than one week after its May 31 premiere, Swamp Thing has been given the axe after only releasing the first of 10 episodes. According to Movies.com writer John Gholson, the abrupt cancelation may be due to an accounting error over a North Carolina tax rebate. He tweets that "North Carolina promised a $40 million tax rebate that, due to a paperwork error, they were unable to deliver. That was roughly half the proposed budget for s1 (which is estimated at $80m). When NC discovered the error, (it was) corrected. WB shut down production, realizing they'd be taking a bath on the rebate and paying for far more of it than assumed. The adjusted number from NC is something like $14m. That's a massive difference." The paperwork error, he points out, made a second season too expensive for the streaming platform. The remaining nine episodes will air as scheduled. Swamp Thing already saw its first season episode order reduced from 13 to 10 episodes in April.
