Dornan released a statement today via his representative to set the record straight:
"Jamie is delighted that the film is breaking box office records worldwide and whilst the studio has not made any formal announcements about sequels, he is looking forward to making the next film."
In addition to that, it was made clear that Dornan would not be making any further statements until the sequels are officially announced. Many sources are now saying that both Dornan and Dakota Johnson have already signed contracts for the sequels and it's just a waiting game until the studio sorts out the problems and announces them. Johnson previously let it slip in an interview with Telegraph that it was a good thing she was excited for the sequels because she has to do them.
I think at this point the best thing to do regarding this franchise is to not believe anything you read or hear unless it's coming directly from Universal.
