Daniel Craig didn't think he was "physically capable" of making another James Bond movie.
The 53-year-old actor had intended to bow out as the suave spy after 2015's Spectre because the gruelling six-month shoot had taken its toll on him and he'd damaged his knee during filming, and he couldn't see any possibility of him returning to the franchise again.
He said: "I thought I probably was physically not capable of doing another. For me, it was very cut and dried that I wasn't coming back."
However, producers weren't ready for him to bow out just yet so knew they needed to give him "some time" to recover before approaching the idea of returning again.
Barbara Broccoli recalled: "He was so exhausted after that film. We'd had our own trials and tribulations on Spectre, and [Daniel] had a massive injury. It was very difficult. So he just needed some time."
