He said: "I've been acting professionally since I was 16 and I'm now 44, so I don't know how to answer the question as to what I would do if I wasn't acting. Even back then at 16, I was so working so hard trying to do this well. I've never really had to look for another job and hopefully I won't have to in the future."
Keanu, who is a big ice-hockey fan, also revealed the only other career he may have chosen to follow was to become a professional sportsman.
He added: "I played ice-hockey when I was an adolescent and maybe that was a crossroads — professional hockey or the high school play. I took the high school play."
