The estate of Michael Crichton, led by his widow Sherri, has filed a lawsuit against Warner Bros. Television, accusing them of creating an unauthorized reboot of the classic medical drama 'ER' with the new show 'The Pitt.' The estate argues that Warner Bros. proceeded with the series after failed negotiations to officially reboot 'ER,' violating a 'frozen rights' provision that prevents any derivatives without their consent. 'The Pitt' is set in Pittsburgh and stars Noah Wyle, who played John Carter in 'ER,' with several other 'ER' alumni involved. Warner Bros. has responded by calling the lawsuit 'baseless' and insists that 'The Pitt' is an original show. The estate claims this move undermines the contractual rights and contributions of one of the industry's most successful creators.
