"I just felt that if I went into Speed 2, I just... wouldn't have come up out of the water"

Keanu Reeves is describing his choice to not appear in the follow up to the film Speed. He is revealing his feeling that if he had actually proceeded with the job, he would not have actually been able to come out of the water. This might be analyzed as a metaphor for his career, suggesting that if he had actually taken the function, it would have been an error that would have dragged him down and he would not have actually been able to recuperate. It might likewise be interpreted as a metaphor for his life, recommending that if he had taken the role, it would have been an error that would have taken him down a course he would not have been able to come back from. In any case, it is clear that Keanu Reeves felt that taking the function in Speed 2 would have been an error and he picked to prevent it.
