Disaster, catastrophe and nightmare. That's how Hollywood's creative workers describe the fall of the once mighty Warner Bros, as Netflix and Paramount battle to buy the historic studio and tinsel town braces for more upheaval and job losses.

Warner's decline and impending sale – whether it's to Paramount Skydance as a whole, or to Netflix cut up in parts – is being mourned in Hollywood, where a historic production slump has already battered the entertainment industry. The loss of the studio, which has created iconic films ranging from Casablanca and Goodfellas to Batman and Harry Potter, likely means more job cuts and definitely means one less buyer of film and TV projects.

Interviews with dozens of actors, producers and camera crews by the BBC reveal an industry attempting to weigh the lesser of two evils: control by a tech giant blamed for killing movie theatres (Netflix) or billionaires seen as too cosy with President Trump (Paramount).

If Netflix gets the deal they want, they will buy Warner Bros' crown jewels – the 102-year-old studio, HBO, and its vast archive of films and TV shows – leaving Warners's legacy TV networks, like CNN, TNT Sports and Discovery, for another buyer.

President Trump further complicates the issue by asserting that it's imperative that CNN be sold. The Warner Bros deal is the latest in a long line of major shake-ups in Hollywood, following a year of labor strikes that hindered production and led to mass layoffs.

As Hollywood grapples with the future of Warner Bros, many industry workers focus on survival as the landscape evolves, highlighting the need for adaptation in a world increasingly influenced by technology.
