If past is present in Hollywood, there's lessons for both David Ellison and David Zaslav from merger mania 100 years ago.

Paramount Skydance on Monday sued Warner Bros ​Discovery for more information on a rival $82.7 billion deal with Netflix , escalating a battle to take control of one of the ‌most storied Hollywood studios.

Warner Bros. blasted Paramount, saying the David Ellison-led company's lawsuit was "yet another unserious attempt to distract and the Judge saw right through it."

According to Variey, this morning Paramount Skydance filed a lawsuit in Delaware court asking that Warner Bros. make public financial details of its decision to accept an $83 billion deal with Netflix. This comes after the board of Warner Bros. rejected Paramount’s $30 per share offer for the entirety of Warner Bros. Discovery.

A judge ruled Paramount hasn't identified “irreparable harm” to itself as a Warner Bros. Discovery shareholder and denied a motion to expedite disclosure.

A Delaware judge dismissed Paramount's motion to expedite the lawsuit against WBD, which is seeking details on how WBD valued the overall Netflix transaction and the proposed Discovery Global networks spin-off.
