Terminator: Genisys has made around $440 million worldwide with just $89 million taken in the US. The Hollywood Reporter says that this, in combination with its $150 million production budget, has caused Paramount to shelve the sci-fi franchise as it's still on course to lose money.
There are question marks over whether a strong Chinese box office performance is enough to save a film. Forbes magazine suggests that Hollywood studios only receive 20-30% of receipts from Chinese cinemas rather than the 50% they’d get in other territories. This would explain why US success is the standard to which studios are holding their movies.
Even Arnold Schwarzenegger's return and a fairly high-profile cast, which included Game of Thrones’ Emilia Clarke and Zero Dark Thirty’s Jason Clarke couldn't save it at the box office.
It looks like Terminator, after all these years, won't be back.
