Halcyon Co. acquired rights to Terminator in May, including sequel rights to Terminator 2 and Terminator 3and a script by T3 writers John Brancato and Michael Ferris, with plans to launch a big-budget sequel.
But MGM has announced that they’re working on the upcoming Terminator movie and Variety reports that the holders of the rights to Terminator 4 have sued MGM, claiming the studio is interfering with their right to negotiate for the distribution of the planned fourth installment of the highly successful series.
