"Sometimes when you make a film you can go away for three months and then come back and live your life. But this struck a much deeper chord. I don't have the ability yet to speak about it in an objective"

Keanu Reeves is describing the extensive effect that making a movie can have on an individual. He suggests that the experience of making a film can be so effective that it can stick with a person long after the recording has actually ended. He implies that the experience has been so profound that he is not yet able to articulate it in an unbiased method. This recommends that the experience has been mentally charged and has had a deep influence on him. It is likely that the experience has been both favorable and negative, and that it has actually left him with a complex set of feelings that he is still trying to process. The quote talks to the power of filmmaking and the effect it can have on the people associated with the procedure.
