In a recent interview with Yahoo, Ryan Reynolds said the only thing that got the Deadpool movie on the fast track was the leaked test footage.
When asked about who leaked it, Reynolds said:
I would have, if I had known it would have caused that! Honestly, we all thought Tim Miller, the director, had leaked it. But I have since investigated that enough, in quiet moments when he was beyond the point of being penalized by anybody, and he said that he really didn’t do it. The initial [leak] came from Fox they think — someone recorded the footage on their iPhone and then released it. And then once that happened, somebody hacked into Blurred Studios and got the original footage in high-res and put it online.Good job, hackers, you did something we like.
