Skydance Productions announced in September 2013 that Terminator Genisys was intended to be the first film in a new stand-alone trilogy. Matt Smith's character, the T-5000, was set to appear in all three films of the new series. In September 2014, Paramount Pictures scheduled the release dates of May 19, 2017 and June 29, 2018 for the sequels to Genisys .   Franchise creator James Cameron will acquire the rights back in 2019, as copyright reversion takes place after 35 years. Cameron will be the beneficiary of changes to the series. 
Before Serenity , Joss Whedon had only directed on the small screen, and if Firefly had been the success we all wanted it to be, he probably would have stayed there. Without Serenity pushing him to make the leap to cinema, Whedon wouldn’t necessarily have been in the running to work on The Avengers. Although he had connections to Marvel, he wouldn’t have had the experience with a feature length production, and the first big Marvel team up may have landed elsewhere. Whether or not you enjoyed his later work for the MCU, there is no doubt that it wouldn’t be what it is today without The Avengers , and that alone is enough of a reason to be thankful that Firefly didn’t come back for season two.
